The morning sky facing north-east in Australia on Friday June 11 at 6:30 am local time showing the Moon and Mercury. the Moon is covering some of the beautiful Pleiades Cluster.On the morning of Friday June 11 the thin crescent Moon is close to Mercury. At this time the Moon also occults the Pleiades Cluster. This will be difficult to see if you don't have a fairly level, clear eastern horizon.You will need a pair of binoculars to see this event at its best (telescopes might be a bit hard to bring to bear as the event is close to the horizon).Times of prominent star disappearances and appearances for major cities are listed here.However, if you start looking from around 6:00 am local time you should see the crescent Moon starkly outlined against the bulk of the Pleiades and various faint and bright stars passing behind the Moon then being revealed.

A study of how climate conditions have affected the origin and evolution of life on Earth could provide clues to understanding how climates on alien planets might affect their potential for life. The Sun used to shine less brightly when the Earth was young, so the early Earth should have been cooler than it is today. Greenhouse gases may have played an important role in warming the planet to a point where it was habitable for life. The study was recently published in the journal Astrobiology.

A tankful of tiny Sea Monkeys were the stars of the show at an Astronomy Day event held in Bozeman, Montana on April 24. The centimeter-long creatures, long the staple of old-school comic book ads, twirled and whirled underwater as kids and adults alike kneeled down for a look. The Sea Monkeys were part of an astrobiology exhibit hosted by Montana State University’s Astrobiology Biogeocatalysis Research Center (ABRC), and the creatures helped spark the conversation about “alien” life. “If we find alien life on another planet, they probably won’t look like the little green men in movies. They’re much more likely to look like this!” said MSU Outreach Specialist Jamie Cornish, as she pointed out the Sea Monkeys’ long tails and three eyes. Sea Monkeys (which are actually a species of brine shrimp) are hardy creatures that have a long track record in space. Cornish said they have flown on the Space Shuttle Discovery, Space Shuttle Endeavour, the USML-1 Columbia, the Space Shuttle Atlantis and the Mir Space Station. Their eggs were placed outside a space vehicle and exposed to the full radiation of the Sun. Upon returning to earth, the eggs still hatched. Cornish told Astronomy Day visitors that ...

Yesterday, I wrote about the comet 2009 R1 McNaught which is currently in the extreme northern sky in the early morning. By coincidence, just hours after posting it, I got an email from the amateur astronomer Anthony Ayiomamitis (the same guy who took the very cool picture of the ISS and Jupiter in the daytime), who sent me this picture of the comet he took in Greece at just around the same time that post went live: Wow, very pretty! The solid part of the comet, called the nucleus, is far smaller than a single pixel in this image, since the comet was more than 175 million km (110 million miles) away when he took this shot. The nucleus of even a huge comet is only a few dozen km across, so at that great distance is just a tiny dot. Anthony has details on his observations on his McNaught page. The comet looks huge — and the fuzzy part can be bigger than planets! — because what you’re seeing is gas expanding away from the nucleus. Far from the Sun that gas is frozen, and the comet is solid. But heat it up, and that ice turns into a ...

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:g Stars - With a mass of more than 10,000 suns packed into a volume with a diameter of a mere three light-years, the massive young star cluster in the nebula NGC 3603 is one of the most compact stellar clusters in the Milky Way and an ideal place to test theories for their formation. See article.g Abodes - New analysis of complex chemical activity on Titan is raising questions about the potential for primitive, exotic life on the Saturnian moon. According to one theory, the chemical signatures fulfill two important conditions necessary for a hypothesized “methane-based life.” See article.g Life - Scientists have discovered methane-eating bacteria that survive in a highly unique spring located on a remote Island in northern Canada. In some ways, the spring could be similar to environments on past or present Mars. See article.g Message - Would anyone deliberately beam high-powered signals into space? Can we assume that extraterrestrial societies would broadcast in ways that would mark their location as plainly as a flag on a golf green? See article. Note: This article is from ...
