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: DESY, Science 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.

Plume from SpaceX Crew-2 Launch https://apod.nasa.gov/apod/ap210424.html

Explanation: What's happening in the sky? The pre-dawn sky first seemed
relatively serene yesterday morning over Indian
Harbor Beach in Florida, USA.
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.

Expedition 53; Music: The Low Seas (The
126ers)
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: NASA, JPL-Caltech, ASU, MSSS
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: NASA, Goddard 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.

Adventure Cinematic Background by Maryna
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 Russian Soyuz-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
Image Credit: Optical: European Southern Observatory (ESO) Wide
Field Imager; Submillimeter: Max Planck Institute for Radio
Astronomy/ESO/Atacama Pathfinder Experiment (APEX)/A.Weiss et al; X-ray and
Infrared: NASA/Chandra/R. Kraft; JPL-Caltech/J. Keene; Text: Joan
Schmelz (USRA)
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: NASA, JPL-Caltech, Event 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 Laboratory; Photographer: 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 York, USA 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
Image Credit: Cassini Imaging Team, ISS, JPL, ESA, NASA
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
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.”
