Gliese 581g – The most habitable exoplanet
 |
This artist’s conception shows the inner four planets of the Gliese 581 system and their host star. The large planet in the foreground is Gliese 581g, which is in the middle of the star’s habitable zone and is only two to three times as massive as Earth. Some researchers aren’t convinced Gliese 581g exists, however.

The controversial exoplanet Gliese 581g is the best candidate to host life beyond our own solar system, according to a new ranking of potentially habitable alien worlds.
Gliese 581g shot to the top of the list — which was published Thursday (July 19) by researchers at the University of Puerto Rico at Arecibo’s Planetary Habitability Laboratory (PHL) — after a new study marshaled support for its long-debated existence.
The exoplanet was discovered in September 2010, but other astronomers began casting doubt on its existence just weeks later. Now Gliese 581g’s discoverers have rebutted their critics’ charges in a new paper, and have done so effectively enough to get the PHL onboard.

Solar Corona Revealed in Super-High-Definition
ScienceDaily (July 20, 2012) — Astronomers have just released the highest-resolution images ever taken of the Sun’s corona, or million-degree outer atmosphere, in an extreme-ultraviolet wavelength of light. The 16-megapixel images were captured by NASA’s High Resolution Coronal Imager, or Hi-C, which was launched on a sounding rocket on July 11th. The Hi-C telescope provides five times more detail than the next-best observations by NASA’s Solar Dynamics Observatory.
These photos of the solar corona, or million-degree outer atmosphere, show the improvement in resolution offered by NASA’s High Resolution Coronal Imager, or Hi-C (bottom), versus the Atmospheric Imaging Assembly on NASA’s Solar Dynamics Observatory (top). Both images show a portion of the sun’s surface roughly 85,000 by 50,000 miles in size. Hi-C launched on a sounding rocket on July 11, 2012 in a flight that lasted about 10 minutes. The representative-color images were made from observations of ultraviolet light at a wavelength of 19.3 nanometers (25 times shorter than the wavelength of visible light). (Credit: NASA)
“Even though this mission was only a few minutes long, it marks a big breakthrough in coronal studies,” said Smithsonian astronomer Leon Golub (Harvard-Smithsonian Center for Astrophysics), one of the lead investigators on the mission.
Understanding the Sun’s activity and its effects on Earth’s environment was the critical scientific objective of Hi-C, which provided unprecedented views of the dynamic activity and structure in the solar atmosphere.

Hubble sees the needle galaxy, edge-on and up close
Image credit: ESA/NASA
This image snapped by the NASA/ESA Hubble Space Telescope reveals an exquisitely detailed view of part of the disc of the spiral galaxy NGC 4565. This bright galaxy is one of the most famous examples of an edge-on spiral galaxy, oriented perpendicularly to our line of sight so that we see right into its luminous disc. NGC 4565 has been nicknamed the Needle Galaxy because, when seen in full, it appears as a very narrow streak of light on the sky.
The edgewise view into the Needle Galaxy shown here looks very similar to the view we have from our Solar System into the core of the Milky Way. In both cases ribbons of dust block some of the light coming from the galactic disc. To the lower right, the dust stands in even starker contrast against the copious yellow light from the star-filled central regions. NGC 4565’s core is off camera to the lower right.

ASTRONOMERS in Chile using a powerful telescope have observed what appears to be evidence of the existence of dark galaxies, the European Southern Observatory (ESO) says.
Dark galaxies are small, gas-rich galaxies from the early universe that are believed to be the building blocks of today’s bright, star-filled galaxies, said the ESO, an intergovernmental organisation supported by 15 countries.
“For the first time, dark galaxies – an early phase of galaxy formation, predicted by theory but unobserved until now – may have been spotted,” the observatory said in a statement on Wednesday.
“Using ESO’s Very Large Telescope, an international team thinks they have detected these elusive objects by observing them glowing as they are illuminated by a quasar,” the statement said.
Giving Ancient Life Another Chance to Evolve: Scientists Place 500-Million-Year-Old Gene in Modern Organism
July 12, 2012
“This is as close as we can get to rewinding and replaying the molecular tape of life,” said scientist Betül Kaçar, a NASA astrobiology postdoctoral fellow in Georgia Tech’s NASA Center for Ribosomal Origins and Evolution. “The ability to observe an ancient gene in a modern organism as it evolves within a modern cell allows us to see whether the evolutionary trajectory once taken will repeat itself or whether a life will adapt following a different path.”

Hubble Discovers a Fifth Moon Orbiting Pluto
ScienceDaily (July 11, 2012) — A team of astronomers using NASA’s Hubble Space Telescope is reporting the discovery of another moon orbiting the icy dwarf planet Pluto.
The moon is estimated to be irregular in shape and 6 to 15 miles across. It is in a 58,000-mile-diameter circular orbit around Pluto that is assumed to be co-planar with the other satellites in the system.
“The moons form a series of neatly nested orbits, a bit like Russian dolls,” said team lead Mark Showalter of the SETI Institute in Mountain View, Calif.
The discovery increases the number of known moons orbiting Pluto to five.
The Pluto team is intrigued that such a small planet can have such a complex collection of satellites. The new discovery provides additional clues for unraveling how the Pluto system formed and evolved. The favored theory is that all the moons are relics of a collision between Pluto and another large Kuiper belt object billions of years ago.

Belching Black Hole Proves a Biggie: First Known ‘Middleweight’ Black Hole
July 10, 2012
-
ScienceDaily (July 9, 2012) — Observations with CSIRO’s Australia Telescope Compact Array have confirmed that astronomers have found the first known “middleweight” black hole.
Outbursts of super-hot gas observed with a CSIRO radio telescope have clinched the identity of the first known “middleweight” black hole, Science Express reports.
Called HLX-1 (“hyper-luminous X-ray source 1”), the black hole lies in a galaxy called ESO 243-49, about 300 million light-years away.
Before it was found, astronomers had good evidence for only supermassive black holes — ones a million to a billion times the mass of the Sun — and “stellar mass” ones, three to thirty times the mass of the Sun.
“This is the first object that we’re really sure is an intermediate-mass black hole,” said Dr Sean Farrell, an ARC Postdoctoral Fellow at the University of Sydney and a member of the research team, which included astronomers from France, Australia, the UK and the USA.

The visual evidence is presented here in two sampling blocks representing the better of the discoveries. In the first block you’ll see quite a few different bodies of water in a liquid state with some of these surrounded by the bonus of very conventional looking forests. The second block is all about samples of large form forest life Mars style none of which are by official consensus suppose to exist at all on this world.
Remember that the Mars surface is officially suppose to be completely dry and devoid of life. Further, the atmosphere is suppose to be 95.35% carbon dioxide (CO2) with only a very tiny .03% of water vapor and super hard frozen to the tune of as much as –220º Fahrenheit or –140º Celsius. In other words it would be a race as to whether an unprotected Earth human out in the open there would be speedily killed by too much poisonous CO2 gas by many times over or quickly frozen to death.
Note that, even though all of the following evidence is in the official science data and available there for verification, you have never heard a peep out of NASA or JPL as to its existence. So this amounts to the hidden Mars that it appears someone in control does not wish you and I to know about or at least also ignore. Also note that I have added a slight bit of false color to these online images to increase clarity and the viewing comfort level. In any case, the high drama visual evidence is as follows.

New Instrument Sifts Through Starlight to Reveal New Worlds
ScienceDaily (July 5, 2012) — An advanced telescope imaging system that started taking data last month is the first of its kind capable of spotting planets orbiting suns outside of our solar system. The collaborative set of high-tech instrumentation and software, called Project 1640, is now operating on the Hale telescope at the Palomar Observatory in California after more than six years of development by researchers and engineers at the American Museum of Natural History, the California Institute of Technology, and the Jet Propulsion Laboratory (JPL).
The project’s first images demonstrating a new technique that creates extremely precise “dark holes” around stars of interest were presented July 5 at the International Society for Optics and Photonics (SPIE) Astronomical Telescopes and Instrumentation meeting in Amsterdam by Ben R. Oppenheimer, a curator in the Museum’s Department of Astrophysics and principal investigator for Project 1640.
Although hundreds of planets are known from indirect detection methods to orbit other stars, it’s extremely difficult to see them directly in an image. This is largely because the light that stars emit is tens of millions to billions of times brighter than the light given off by planets.

Evidence of Life On Mars Could Come from Martian Moon Phobos
ScienceDaily (June 29, 2012) — A mission to a Martian moon could return with alien life, according to experts at Purdue University, but don’t expect the invasion scenario presented by summer blockbusters like “Men in Black 3” or “Prometheus.”
“We are talking little green microbes, not little green men,” said Jay Melosh, a distinguished professor of earth, atmospheric and planetary sciences and physics and aerospace engineering at Purdue. “A sample from the moon Phobos, which is much easier to reach than the Red Planet itself, would almost surely contain Martian material blasted off from large asteroid impacts. If life on Mars exists or existed within the last 10 million years, a mission to Phobos could yield our first evidence of life beyond Earth.”
