AEA Astronomy Club meetings are now on 1st  Thursdays at 11:30 am.  For 2020:  Jan. & Feb. in A1/1735, March 5 in A1/2906 and for the rest of 2020 (April to Dec.) virtual meetings on Teams. 

 

Club News:  

 

We understand that several club members have signed on for the Antarctic Eclipse cruise later this year.  We wish them smooth sailing and clear skies, and look forward to their report and photos.

 

We need volunteers to help with:

·         Assembling our new 16-inch Hubble Optics Dobs

·         Installing our new software on our tablet & laptop

·         Populating our club Sharepoint site with material & links to the club’s Aerowiki & Aerolink materials – Kaly Rangarajan has volunteered to help with this

·         Arranging future club programs

·         Managing club equipment & library (Kelly Gov volunteered to help with the library)

 

For the 2024 (April 8) eclipse, here is some new data on cloudiness & duration of totality along the eclipse path.  There is clearly some improvement in cloud fraction in Mexico vs Texas.  Though the negatives of going into Mexico are not inconsiderable, and with some mobility on eclipse day it should be possible to find adequate clearing near San Antonio.  Hotels will be taking reservations starting next April, so we will need to get RSVPs by then for a count & group rates.

 



 

Astronomy Video(s) & Picture(s) of the Month

(generally from Astronomy Picture of the Day, APOD: http://apod.nasa.gov/apod/archivepix.html)

VIDEO:  Animation: Black Hole Destroys Star  https://apod.nasa.gov/apod/ap210427.html
Video Illustration Credit: DESYScience Communication Lab

Explanation: What happens if a star gets too close to a black hole? The black hole can rip it apart -- but how? It's not the high gravitational attraction itself that's the problem -- it's the difference in gravitational pull across the star that creates the destruction. In the featured animated video illustrating this disintegration, you first see a star approaching the black hole. Increasing in orbital speed, the star's outer atmosphere is ripped away during closest approach. Much of the star's atmosphere disperses into deep space, but some continues to orbit the black hole and forms an accretion disk. The animation then takes you into the accretion disk while looking toward the black hole. Including the strange visual effects of gravitational lensing, you can even see the far side of the disk. Finally, you look along one of the jets being expelled along the spin axis. Theoretical models indicate that these jets not only expel energetic gas, but create energetic neutrinos -- one of which may have been seen recently on Earth.

Explanation: What's happening in the sky? The pre-dawn sky first seemed relatively serene yesterday morning over Indian Harbor Beach in FloridaUSA. But then it lit up with a rocket launch. Just to the north, NASA's SpaceX Crew-2 Mission blasted into space aboard a powerful Falcon 9 rocket. The featured time-lapse video -- compressing 12-minutes into 8-seconds -- shows the bright launch plume starting on the far left. The rocket rises into an increasingly thin atmosphere, causing its plume to spread out just as it is lit by the rising Sun. As the Crew-2 capsule disappears over the horizon, the landing plume of the returning first stage of the Falcon 9 descending toward the SpaceX barge in the Atlantic Ocean can be seen. Up in space, the Endeavour crew capsule is expected to dock with the International Space Station (ISS) this morning, delivering four astronauts. The Crew-2 astronauts join Expedition 65 to help conduct, among other tasks, drug tests using tissue chips -- small microfluidic chips that simulate human organs -- that run rapidly in ISS's microgravity.

Explanation: Recorded during 2017, timelapse sequences from the International Space Station are compiled in this serene video of planet Earth at Night. Fans of low Earth orbit can start by enjoying the view as green and red aurora borealis slather up the sky. The night scene tracks from northwest to southeast across North America, toward the Gulf of Mexico and the Florida coast. A second sequence follows European city lights, crosses the Mediterranean Sea, and passes over a bright Nile river in northern Africa. Seen from the orbital outpost, erratic flashes of lightning appear in thunder storms below and stars rise above the planet's curved horizon through a faint atmospheric airglow. Of course, from home you can always check out the vital signs of Planet Earth Now.

VIDEO:  Ingenuity: First Flight over Mars https://apod.nasa.gov/apod/ap210420.html
Video Credit: NASAJPL-CaltechASUMSSS

Explanation: What's the best way to explore Mars? Perhaps there is no single best way, but a newly demonstrated method shows tremendous promise: flight. Powered flight has the promise to search vast regions and scout out particularly interesting areas for more detailed investigation. Yesterday, for the first time, powered flight was demonstrated on Mars by a small helicopter named Ingenuity. In the featured video, Ingenuity is first imaged by the Perseverance rover sitting quietly on the Martian surface. After a few seconds, Ingenuity's long rotors begin to spin, and a few seconds after that -- history is made as Ingenuity actually takes off, hovers for a few seconds, and then lands safely. More tests of Ingenuity's unprecedented ability are planned over the next few months. Flight may help humanity better explore not only Mars, but Saturn's moon Titan over the next few decades.

VIDEO:  The Doubly Warped World of Binary Black Holes https://apod.nasa.gov/apod/ap210416.html
Scientific Visualization Credit: NASAGoddard Space Flight Center, Jeremy Schnittman and Brian P. Powell - Text: Francis Reddy

Explanation: Light rays from accretion disks around a pair of orbiting supermassive black holes make their way through the warped space-time produced by extreme gravity in this stunning computer visualization. The simulated accretion disks have been given different false color schemes, red for the disk surrounding a 200-million-solar-mass black hole, and blue for the disk surrounding a 100-million-solar-mass black hole. That makes it easier to track the light sources, but the choice also reflects reality. Hotter gas gives off light closer to the blue end of the spectrum and material orbiting smaller black holes experiences stronger gravitational effects that produce higher temperatures. For these masses, both accretion disks would actually emit most of their light in the ultraviolet though. In the video, distorted secondary images of the blue black hole, which show the red black hole's view of its partner, can be found within the tangled skein of the red disk warped by the gravity of the blue black hole in the foreground. Because we're seeing red's view of blue while also seeing blue directly, the images allow us to see both sides of blue at the same time. Red and blue light originating from both black holes can be seen in the innermost ring of light, called the photon ring, near their event horizons. Astronomers expect that in the not-too-distant future they’ll be able to detect gravitational waves, ripples in space-time, produced when two supermassive black holes in a system much like the one simulated here spiral together and merge.

Explanation: Have you ever seen a rocket launch -- from space? A close inspection of the featured time-lapse video will reveal a rocket rising to Earth orbit as seen from the International Space Station (ISS). The RussiaSoyuz-FG rocket was launched in November 2018 from the Baikonur Cosmodrome in Kazakhstan, carrying a Progress MS-10 (also 71P) module to bring needed supplies to the ISS. Highlights in the 90-second video (condensing about 15-minutes) include city lights and clouds visible on the Earth on the lower left, blue and gold bands of atmospheric airglow running diagonally across the center, and distant stars on the upper right that set behind the Earth. A lower stage can be seen falling back to Earth as the robotic supply ship fires its thrusters and begins to close on the ISS, a space laboratory that celebrated its 20th anniversary in 2018. Astronauts who live aboard the Earth-orbiting ISS conduct, among more practical duties, numerous science experiments that expand human knowledge and enable future commercial industry in low Earth orbit.

 

Centaurus A's Warped Magnetic Fields

Explanation: When galaxies collide -- what happens to their magnetic fields? To help find out, NASA pointed SOFIA, its flying 747, at galactic neighbor Centaurus A to observe the emission of polarized dust -- which traces magnetic fields. Cen A's unusual shape results from the clash of two galaxies with jets powered by gas accreting onto a central supermassive black hole. In the resulting featured image, SOFIA-derived magnetic streamlines are superposed on ESO (visible: white), APEX (submillimeter: orange), Chandra (X-rays: blue), and Spitzer (infrared: red) images. The magnetic fields were found to be parallel to the dust lanes on the outskirts of the galaxy but distorted near the center. Gravitational forces near the black hole accelerate ions and enhance the magnetic field. In sum, the collision not only combined the galaxies’ masses -- but amplified their magnetic fields. These results provide new insights into how magnetic fields evolved in the early universe when mergers were more common.

The Galaxy, the Jet, and a Famous Black Hole
Image Credit: NASAJPL-CaltechEvent Horizon Telescope Collaboration

Explanation: Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured by planet Earth's Event Horizon Telescope in the first ever image of a black hole. Giant of the Virgo galaxy cluster about 55 million light-years away, M87 is the large galaxy rendered in blue hues in this infrared image from the Spitzer Space telescope. Though M87 appears mostly featureless and cloud-like, the Spitzer image does record details of relativistic jets blasting from the galaxy's central region. Shown in the inset at top right, the jets themselves span thousands of light-years. The brighter jet seen on the right is approaching and close to our line of sight. Opposite, the shock created by the otherwise unseen receding jet lights up a fainter arc of material. Inset at bottom right, the historic black hole image is shown in context, at the center of giant galaxy and relativistic jets. Completely unresolved in the Spitzer image, the supermassive black hole surrounded by infalling material is the source of enormous energy driving the relativistic jets from the center of active galaxy M87.

The Pencil Nebula Supernova Shock Wave
Image Credit & Copyright: Greg Turgeon & Utkarsh Mishra

Explanation: This supernova shock wave plows through interstellar space at over 500,000 kilometers per hour. Near the middle and moving up in this sharply detailed color composite, thin, bright, braided filaments are actually long ripples in a cosmic sheet of glowing gas seen almost edge-on. Cataloged as NGC 2736, its elongated appearance suggests its popular name, the Pencil Nebula. The Pencil Nebula is about 5 light-years long and 800 light-years away, but represents only a small part of the Vela supernova remnant. The Vela remnant itself is around 100 light-years in diameter, the expanding debris cloud of a star that was seen to explode about 11,000 years ago. Initially, the shock wave was moving at millions of kilometers per hour but has slowed considerably, sweeping up surrounding interstellar material. In the featured narrow-band, wide field image, red and blue colors track, primarily, the characteristic glows of ionized hydrogen and oxygen atoms, respectively.

Confirmed Muon Wobble Remains Unexplained
Image Credit: Fermi National Accelerator LaboratoryPhotographer: Reidar Hahn

Explanation: How fast do elementary particles wobble? A surprising answer to this seemingly inconsequential question came out of Brookhaven National Laboratory in New YorkUSA in 2001, and indicated that the Standard Model of Particle Physics, adopted widely in physics, is incomplete. Specifically, the muon, a particle with similarities to a heavy electron, has had its relatively large wobble under scrutiny in a series of experiments known as g-2 (gee-minus-two). The Brookhaven result galvanized other experimental groups around the world to confirm it, and pressured theorists to better understand it. Reporting in last week, the most sensitive muon wobble experiment yet, conducted at Fermi National Accelerator Laboratory (Fermilab) in Illinois and pictured here, agreed with the Brookhaven result. The unexpected wobble rate may indicate that an ever-present sea of virtual particles includes types not currently known. Alternatively, it may indicate that flaws exist in difficult theoretical prediction calculations. Future runs at Fermilab's g-2 experiment will further increase precision and, possibly, the statistical difference between the universe we measure and the universe we understand.

In, Through, and Beyond Saturn's Rings

Explanation: Four moons are visible on the featured image -- can you find them all? First -- and farthest in the background -- is Titan, the largest moon of Saturn and one of the larger moons in the Solar System. The dark feature across the top of this perpetually cloudy world is the north polar hood. The next most obvious moon is bright Dione, visible in the foreground, complete with craters and long ice cliffs. Jutting in from the left are several of Saturn's expansive rings, including Saturn's A ring featuring the dark Encke Gap. On the far right, just outside the rings, is Pandora, a moon only 80-kilometers across that helps shepherd Saturn's F ring. The fourth moon? If you look closely inside Saturn's rings, in the Encke Gap, you will find a speck that is actually Pan. Although one of Saturn's smallest moons at 35-kilometers across, Pan is massive enough to help keep the Encke gap relatively free of ring particles. After more than a decade of exploration and discovery, the Cassini spacecraft ran low on fuel in 2017 and was directed to enter Saturn's atmosphere, where it surely melted.

 

Astronomy News:

 

The Milky Way may have grown up faster than

 astronomers suspected

Most of the galaxy’s disk was in place before a major collision 10 billion years ago

Much of the Milky Way’s characteristic disk (seen edge-on in this image from the Gaia spacecraft) was already in place 10 billion years ago, when an interloper galaxy called Gaia-Enceladus/Sausage collided with it.

DPAC/GAIA/ESA (CC BY-SA 3.0 IGO)

The Milky Way as we know it today was shaped by a collision with a dwarf galaxy about 10 billion years ago. But most of the modern galaxy was already in place even at that early date, new research shows.

Ages of stars left behind by the galactic interloper are a bit younger or on par with stars in the Milky Way’s main disk, researchers report May 17 in Nature Astronomy. And that could mean that the Milky Way grew up faster than astronomers expected, says study author Ted Mackereth, an astrophysicist at the University of Toronto.

“The Milky Way had already built up a lot of itself before this big merger happened,” he says.

Our galaxy’s history is one of violent conquest. Like other giant spiral galaxies in the universe, the Milky Way probably built up its bulk by colliding and merging with smaller galaxies over time. Stars from the unfortunate devoured galaxies got mixed into the Milky Way like cream into coffee, making it difficult to figure out what the galaxies were like before they merged.

In 2018, astronomers realized that they could identify stars from the last major merger using detailed maps of several million stars from the European Space Agency’s Gaia spacecraft (SN: 5/9/18). Streams of stars orbit the galactic center at an angle to the main disk of stars. Those stars’ motions and chemistries suggest they once belonged to a separate galaxy that plunged into the Milky Way about 10 billion years ago (SN: 11/1/2018).

“Those stars are left there like fossil remnants of the galaxy,” Mackereth says.

Two groups discovered evidence of the ancient galaxy at around the same time. One called the galaxy Gaia-Enceladus; the other group called it the Sausage. The name that stuck was Gaia-Enceladus/Sausage.

Mackereth and his colleagues wondered if they could figure out how well developed the Milky Way was when Gaia-Enceladus/Sausage came crashing in. If the oldest stars in the Milky Way’s disk formed after this merger, then they probably formed as a result of this collision, suggesting that Gaia-Enceladus/Sausage met a proto–Milky Way that still had a lot of growing up to do. On the other hand, if the oldest stars are about the same age or older than the stars from the galactic interloper, then our galaxy was probably pretty well developed at the time of the run-in. 

Previous researchers had made estimates. But Mackereth and his colleagues used a precise tool called asteroseismology to figure out the ages of individual stars from both the Milky Way and from Gaia-Enceladus/Sausage (SN: 8/2/19). Just like seismologists on Earth use earthquakes to probe the interior of our planet, asteroseismologists use variations in brightness caused by starquakes and other oscillations to probe the innards of stars.

“Asteroseismology is the only way we have to access the internal part of the stars,” says physicist and study coauthor Josefina Montalbán of the University of Birmingham in England. From intel on the star’s interior structures, researchers can deduce the stars’ ages.

The team selected about 95 stars that had been observed by NASA’s exoplanet-hunting Kepler space telescope, which ended its mission in 2018 (SN: 10/30/18). Six of those stars were from Gaia-Enceladus/Sausage, and the rest were from the Milky Way’s thick disk. By measuring how the brightnesses of those stars fluttered over time, Mackereth and colleagues deduced ages with about 11 percent precision.

The Gaia-Enceladus/Sausage stars are slightly younger than the Milky Way stars, but all were pretty close to 10 billion years old, the team found. That suggests that a large chunk of the Milky Way’s disk was already in place when Gaia-Enceladus/Sausage came crashing through. It’s still possible that the incoming galaxy sparked the formation of some new stars, though, Mackereth says. To tell how much, they’ll need to get ages of a lot more stars.

Measuring ages for individual stars represents a step forward for galactic astronomy, says astrophysicist Tomás Ruiz-Lara of the University of Groningen, the Netherlands, who studies galactic evolution but was not involved in the new work.

“If you cannot tell the difference between a kid and a teenager and an adult, then we cannot say anything” about a population of people, Ruiz-Lara says. “But if I can distinguish between someone in his 40s or her 50s, you have a better graph of society. With the stars, it’s the same. If we are able to distinguish the age properly, then we can distinguish individual events in the history of the galaxy. In the end, that’s the goal.”
