NASA finds over 100 billion tons of ice on Mercury

NASA scientists have discovered that Mercury, the closest planet to the sun, is home to a whole lot of ice. This, of course, is the same planet that gets ridiculously hot around its equator, to the tune of about 800-degrees Fahrenheit. There has been speculation for quite some time that the craters located on the planet’s poles might contain ice; now we have confirmation thanks to scientists working with the Messenger mission.

Senior scientist at John Hopkin’s Applied Physics Laboratory David Lawrence, who is part of the Messenger mission, said, “In these planetary bodies, there are hidden places, as it were, that can have interesting things going on.” He’s referring to the deep craters located near Mercury’s poles, which, due to their position, do not get sunlight. In the absence of sunlight, temperatures plummet, reaching lows as cold as -370F degrees.

While the temperatures reach exceedingly cold temperatures and scientists have speculated that the craters contain ice, it was possible that they were lined with some type of reflective substance, such as sulfur. To verify that it was indeed ice, Messenger scientists used the same method that was used to find ice on Mars and the Moon. Researchers counted neutrons originating from the planet, which decreased as Messenger moved over the icy spots, indicating the presence of frozen water.

The findings were published today in the journal Science‘s website in three different batches. The icy areas have been proposed as possible landing regions for robots in the here and now, and possibly a source of water for future colonies placed in locations on Mercury where the temperatures aren’t so extreme. Said geology professor at UCLA David Paige, “People joke about it, but it’s not so crazy, really.”

NASA Finds Water and Organic Matter In Mercury

NASA has confirmed a surprising, counterintuitive discovery. The burning hell known Mercury—the closest planet to the Sun—has water. Frozen water. Three new research papers, based on data obtained by the Messenger spacecraft, show undeniable evidence. More »

Penumbral lunar eclipse scheduled for 6AM PST tomorrow

Tomorrow at about 6AM Pacific time, if you’re not unlucky enough to have an overcast sky, you’ll be able to observe a penumbral lunar eclipse. This happens when the Earth moves between the moon and sun, and the moon ends up under Earth’s penumbra. According to NASA, the eclipse will be at its greatest around 6:33am, and will be visible until around 7am.

Because of the way a penumbral eclipse manifests, viewers will not see a defined shape, instead being presented with a shadow that grows dimmer as the planets move. This makes it a bit harder to observe; you’ll have the best chance of seeing it when the eclipse is at its peak, assuming no clouds or fog get in the way.

Both the beginning and the end of a penumbral eclipse are not visible, with the visible eye being able to detect it once the moon is about two-thirds into the Earth’s penumbra. This falls between the PST hours of 6am and 7am. This is the last lunar eclipse of 2012; it has a magnitude of 0.9155, according to Wunderground.com.

If you’re in the mood for a bit of science, NASA has a list of all lunar eclipses in the Saros 145 cycle up on its website, which you can view via the link below. Each Saros cycle is a little over 18 years long, with tomorrow’s eclipse being part of the Saros Series 145. Says NASA: “Lunar eclipses of Saros 145…began with a penumbral eclipse near the southern edge of the penumbra on 1832 Aug 11. The series will end with a penumbral eclipse near the northern edge of the penumbra on 3094 Sep 16.”

University of Montreal detects an orbitless planet, shows that stars don’t have an iron grip (video)

University of Montreal successfully spots an orbitless planet, shows that stars don't have an iron grip

Astronomers have long theorized that there are many planets that have drifted away from their home stars, whether it’s a too-loose gravitational pull during the planet’s formation or a stellar tug-of-war. We’ve never had a reasonable chance of locating such a wanderer until today, however. The University of Montreal believes it has spotted CFBDSIR2149, an awkwardly-named gas giant four to seven times larger than Jupiter, floating by itself in the AB Doradus Moving Group of young stars. Scientists made the discovery first by pinpointing their target through infrared images from the Canada-France-Hawaii Telescope, and later using the Very Large Telescope to deduce that the object was both too small to be a star as well as hot and young enough (752F and under 120 million years old) to fit the behavior of a planet orphaned early into its existence. With CFBDSIR2149’s nature largely locked down, the challenge now is learning just how common such lonely examples can be; when it’s much easier to focus on the stars while hunting for planets, finding any more strays could prove to be a daunting task.

This May Be the First Confirmed Errant Planet Detected by Humans

This bright blue marble is CFBDSIR2149. Located only 100 light-years away from Earth, this lonely cyan gem may be the very first errant planet detected by humans. And apparently it’s quite beautiful, looking similar to Neptune* while being four to seven times as big as Jupiter. More »

DARPA SpaceView program enlists us to track space debris, save a satellite today (video)

DARPA SpaceView program enlists us to track space debris, save a satellite today

Space junk is an undeniable problem when there’s over 500,000 dead satellites, spacecraft pieces and other human-made obstacles that could crash into active orbiting vehicles. DARPA is more than a little overwhelmed in trying to track all those hazards by itself, so it’s recruiting amateur help through its new SpaceView program. The effort will buy time for non-professional astronomers on existing telescopes, or even supply hardware directly, to track the spaceborne debris without the sheer expense of growing an existing surveillance network. While that amounts to using hobbyists purely as volunteers, DARPA notes that the strategy could be a win-win for some when hardware donated for SpaceView could be used for regular astronomy in spare moments. The challenge is getting through the sign-up phase. While SpaceView is taking applications now, it’s initially focusing on options for standard commercial telescopes and hand-picking those who have permanent access to hardware in the right locations — there’s no guarantee a backyard observatory will pass muster. Those who do clear the bar might sleep well knowing that satellites and rockets should be that much safer in the future.
