NASA’s Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory’s drill. “This temporary increase in methane—sharply up and then back down—tells us there must be some relatively localized source,” said Sushil Atreya of the University [...]

A team of scientists, led by Dr. Sebastian Hoenig from the University of Southampton, has measured the distance to the NGC 4151 (“Eye of Sauron”) galaxy with unprecedented accuracy, using the W. M. Keck Observatory Interferometer in Hawaii. The team employed a new technique they developed, which allows them to measure distances to galaxies tens of millions of light-years away with 90 [...]

Scientists have produced a new version of what is perhaps NASA’s best view of Jupiter’s ice-covered moon, Europa. The mosaic of color images was obtained in the late 1990s by NASA’s Galileo spacecraft. This is the first time that NASA is publishing a version of the scene produced using modern image processing techniques. The image features many long, curving and linear fractures in the [...]

With the Philae lander’s mission complete, Rosetta will now continue its own extraordinary exploration, orbiting Comet 67P/Churymov–Gerasimenko during the coming year as the enigmatic body arcs ever closer to our Sun. Last week, ESA’s Rosetta spacecraft delivered its Philae lander to the surface of the comet for a dramatic touchdown. The lander’s planned mission ended after about 64 [...]

On Nov. 12, ESA’s Rosetta mission made history by soft-landing its Philae probe on a comet, the first time such an extraordinary feat has been achieved. After a tense wait during the seven-hour descent to the surface of Comet 67P/Churyumov-Gerasimenko, the signal confirming the successful touchdown arrived on Earth at 16:03 GMT (8:03 a.m. PST). “Our ambitious Rosetta mission has secured [...]

The site where Rosetta’s Philae lander is scheduled to touch down on Comet 67P/Churyumov-Gerasimenko November 12 now has a name: Agilkia. The landing site, previously known as “Site J,” is named for Agilkia Island on the Nile River in the south of Egypt. A complex of Ancient Egyptian buildings, including the famous Temple of Isis, was moved to Agilkia from the island of Philae when the [...]

Using an array of 6 telescopes at Mount Wilson Observatory  astronomers have observed the expanding thermonuclear fireball from a “nova” that erupted last year in the constellation Delphinus. The observations produced the first images of a nova during the early fireball stage and revealed how the structure of the ejected material evolves as the gas expands and cools. The results of these [...]

The longest-lived robot ever sent to Mars came through its latest challenge in good health, reporting home on schedule after sheltering behind Mars from possible comet dust. NASA’s Mars Odyssey was out of communications with Earth, as planned, while conducting observations of comet C/2013 A1 Siding Spring on Sunday, Oct. 19, as the comet flew near Mars. The comet sped within about 88,000 [...]

A partial eclipse of the sun will be visible across most of North America on Thursday, October 23, as the Moon partially obscures the Sun between 2:10 and 4:40 p.m. PDT. At eclipse maximum (3:29 p.m.) the Sun will be approximately half covered, as the Moon passes in front of it. Viewers should exercise extreme caution to avoid eye damage. NEVER look directly at the Sun except through [...]

NASA’s Astrobiology Institute (NAI) announced that the SETI Institute has been selected as a new member of the NAI for a 5-year research program, “Changing Planetary Environments and the Fingerprints of Life.” Led by SETI’s planetary geologist and Senior Research Scientist Nathalie Cabrol, the team’s work will address key questions: How can we identify the signature of life not just [...]
