M106 Close Up

Explanation: Close to the Great Bear (Ursa Major) and surrounded by the stars of the Hunting Dogs (Canes Venatici), this
celestial wonder was discovered in 1781 by the metric French astronomerPierre Mechain. Later, it was added to
the catalog of his friend and colleague Charles Messier as M106. Modern deep telescopic views reveal it to be an island universe: a spiral galaxy around 30 thousand light-years
across located only about 21 million light-years beyond the stars of the Milky
Way. Along with prominent dust lanes and a bright central core, this colorful composite image highlights youthful blue star clusters and reddish stellar
nurseries that trace the galaxy's spiral arms. The high resolution galaxy portrait is
a mosaic of data from Hubble's sharp ACS camera combined with groundbased color
image data. M106 (aka NGC 4258) is a nearby example of the Seyfert class of active galaxies, seen across the spectrum from radio to X-rays. Energetic active galaxies are powered
by matter falling into a massive central black hole.Credit: Composite Image Data - Hubble Legacy Archive; Adrian Zsilavec, Michelle Qualls, Adam Block / NOAO / AURA / NSF

Hubble Remix: Active
Galaxy NGC 1275
Image Credit: Data - Hubble Legacy Archive, ESA, NASA; Processing - Al Kelly
Explanation: Active galaxy NGC 1275 is the central, dominant member of the large and
relatively nearby Perseus Cluster of Galaxies. Wild-looking at
visible wavelengths, the active galaxy is also a prodigious source of x-rays and radio emission. NGC 1275 accretes matter as entire galaxies fall
into it, ultimately feeding a supermassive black hole at the galaxy's core.
This color composite image, recreated from archival
Hubble Space Telescope data, highlights the resulting galactic debris and filaments of glowing gas, some up
to 20,000 light-years long. The filaments persist in NGC 1275, even though the turmoil of galactic collisions
should destroy them. What keeps the filaments together? Observations indicate that the
structures, pushed out from the galaxy's center by the black hole's activity,
are held together by magnetic fields. Also known as Perseus A, NGC 1275 spans over 100,000 light years and lies about 230 million
light years away.Image Credit: Data - Hubble Legacy Archive, ESA, NASA; Processing - Al Kelly

Explanation: How impressive will Comet ISON become? No one is sure, but unfortunately, as the comet approaches the inner Solar System, it is brightening more slowly than many early predictions.Pictured above, Comet ISON is seen about two weeks ago as >it continued to develop a tail. Last week the comet passed relatively close to Mars, and was directly imaged by the Mars Reconnaissance Orbiter. When Comet ISON dives to within a few solar radii of the Sun's >surface in late November, it may become brighter than the Moon and sport a long and >flowing tail -- or it may appear somewhat less spectacular. Either way, sky enthusiasts hope that whatever comet parts survive will put on quite an impressive show, as viewed from Earth, through at least the rest of the year.
Astronomy News:
Scientists
Calculate 40 Billion Earth-Sized Planets Exist In The Milky Way Galaxy.
AIAA Daily Launch 5 November 2013:
The CBS Evening News
broadcast that NASA announced on Monday that there may be “40 billion
Earth-sized planets” in the Milky Way in the habitable zones of their parent
stars, called the “Goldilocks Zone” for being “not too hot, not too cold” for
potential life.
The AP (11/5, Borenstein)
reports the findings are based on years of observations from the “now-crippled”
Kepler telescope. Geoff Marcy of UC Berkeley co-authored the study that found
that about “1 in 5 stars” in our galaxy have Earth-sized planets. Bill Borucki,
NASA’s chief Kepler scientist, “joked” that “you’d probably see a lot of
traffic jams” if humans could travel far enough into space. According to the
article, this is the first calculation, not estimation, of how many Earth-sized
planets are in their stars’ habitable zones. Meanwhile, the article notes that
at a “Kepler science conference,” scientists also announced the Kepler
telescope found “833 new candidate planets,” but most of these were not
“candidates for life.”
The New York Times (11/5, Overbye,
Subscription Publication) calls the new calculation of the number of habitable
planets in the galaxy the result of a “herculean” study led by Erik Petigura of
UC Berkeley. Natalie Batalha of the Ames Research Center said this project was
“the best of humanity rising to the occasion.” The article also credited Petigura
with developing a new way of testing to see how efficient their detection
program was by inserting “fake planets” into the data. According to the
article, Batalha stressed that even with the Kepler telescope “sidelined,”
there is still over a year of data to sift through, so “scientists...are going
to work on Kepler data for decades.” Meanwhile, Sara Seager of MIT said Kepler
was “dead,” so researchers have to be “satisfied” with what it has produced.
The Washington Post (11/5, Achenbach)
reports that Seager said the results should “boost” efforts to develop more
telescopes that could continue Kepler’s work. Meanwhile, SETI “pioneer” Jill
Tarter said the results indicate someone should discover “Earth 2.0” relatively
soon. The article stressed that all this study determined was the number of
planets the same relative size as Earth, but could not say how closely any
resemble Earth.
The CBS News (11/5, Harwood)
website reports Borucki said more research is needed to determine how habitable
these planets are, adding “Planets with CO2 (carbon dioxide) and water vapor,
which is what you need for life, I think we’ll find are probably fairly common
in our galaxy. ... That’s certainly speculation at this point. We need to go
out and make those measurements so we’re not guessing.” He also said, “We’re
celebrating opening a new era in astronomy, we’re beginning the exploration of
our galaxy. ... Imagine what (future) missions will find as we continue that
exploration.”
Meanwhile, Reuters (11/5, Klotz) has
further coverage of the other Kepler study by Jason Rowe of the SETI Institute,
which found that of 3,538 candidate planets, 647 are about the size of Earth.
Also covering the story
are the Los Angeles Times (11/5, Khan) “Science
Now” blog, San Francisco Chronicle (11/5, Perlman), AFP (11/5), Bloomberg News (11/5, Ostrow), NPR (11/5, Neuman) “The
Two-Way” blog, Voice of America (11/5), the Atlantic (11/5, Garber), and
other media sources.
Kepler’s Future Expected
To Be Discussed At Second Kepler Science Conference. In an article for the Space Review (11/4), Space Review
editor Jeff Foust wrote on recent exoplanet discoveries, including Petigura’s
study, as well as the Second Kepler Science Conference. Foust noted that one
issue expected to be discussed at the conference is possible future uses for
Kepler as managers are now reviewing 40 proposals. Batalha said during a
teleconference Friday, “They were subjected to review and scrutiny by the
engineers to try and decide what was feasible and what is scientifically
compelling. ... We will be submitting a report to NASA Headquarters soon, later
this month, to summarize the results of that study.” Batalha added that
researchers also want to continue to refine the collected Kepler data, saying,
“What we’d like to do to make up for not having as much data as we’d thought
we’d have is to really dive down into the weeds and apply innovative techniques
to give Erik [Petigura] better brightness measurement.” Marcy also said Friday
that NASA took a “bold move” launching Kepler in the first place, adding it was
a “joy” to work with the team.

From IRAS to Spitzer and Beyond: 30 years of Space-Based
Infrared Astronomy
The infrared lies
beyond the red end of the visible spectrum of light. Cool and dusty things
throughout the Universe appear bright in infrared. 2013 is a significant year
in infrared astronomy -- it marks the 30th anniversary of the launch of IRAS,
the Infrared Astronomical Satellite, which revolutionized our view of the
infrared cosmos, increasing the number of known infrared sources by about 70%.
It's also the 10th anniversary of the launch of the Spitzer Space Telescope, at
the time the most sensitive infrared telescope ever built, which has helped
revolutionize our understanding of galaxy evolution, exoplanets, and star
formation. 2013 is also the 4th anniversary of the launch of the infrared
missions Herschel and WISE, the Wide-Field Infrared Survey Explorer. This talk
will review some of the major discoveries from each of these important infrared
astronomy missions.
