[Monday, April 2, 2007] For the first time in the history of planetary exploration, topographic maps of the Martian sub-soil have been produced, revealing considerable volumes of ice.

[Wednesday, April 4, 2007] We report evidence for a planetary companion around the nearby young star HD 70573. The star is a G type dwarf located at a distance of 46 pc with age estimation between 20 and 300 Myrs.

[Wednesday, April 4, 2007] "Hi, I'm Jesse Carpenter and you're listening to a podcast presented in three parts. Launched in 1999 the Stardust spacecraft collected dust particles from the tail of the comet Wild 2 in 2004 and returned the samples to Earth in 2006. "

[Friday, April 6, 2007] LOCAD-PTS (short for Lab-On-a-Chip Application Development–Portable Test System), is a mini-lab detects the presence of bacteria or fungi on the surfaces of a spacecraft far more rapidly than standard methods of culturing.

[Friday, April 6, 2007] NASA scientists have discovered evidence that a mysterious red glow, seen throughout the Milky Way and other galaxies but never on Earth, radiates from extremely fine dust clusters that cause the glow by combining molecular forces that oppose each other.

[Sunday, April 8, 2007] NAU researchers Glen Cushing and Jut Wynne, working at the U.S. Geological Survey, propose that photos from the Mars Odyssey mission reveal football-field size holes that could be entrances to caves.

[Tuesday, April 10, 2007] For the first time, water has been identified in the atmosphere of an extrasolar planet. Through a combination of previously published Hubble Space Telescope measurements and new theoretical model.

[Wednesday, April 11, 2007] In the next decade, when scientists are able to study Earth-sized worlds around other stars, they may find that foliage on some of the planets is predominantly yellow--or orange, or red.

[Wednesday, April 11, 2007] For the first time ever, NASA researchers have successfully demonstrated in the laboratory that a space telescope rigged with special masks and mirrors could snap a photo of an Earth-like planet orbiting a nearby star.

[Thursday, April 12, 2007] Darwin will look for extrasolar planets and signs of life. ESA's Technology Research Program has sponsored the development of critical optical components whose frictionless mechanism can respond to the touch of a feather.

[Wednesday, April 18, 2007] The closer a young, maverick star happens to be to a super hot O-star, the more likely its burgeoning planets will be blasted into space.

[Wednesday, April 18, 2007] Astronomers have laid down the cosmic equivalent of yellow "caution" tape around super hot stars, marking the zones where cooler stars are in danger of having their developing planets blasted away.

[Sunday, April 22, 2007] New research shows that black holes are not the ultimate destroyers that are often portrayed in popular culture. Instead, warm gas escaping from the clutches of enormous black holes could be one source of the chemical elements that make life possible. 

[Sunday, April 22, 2007] A new "black smoker"--an undersea mineral chimney emitting hot springs of iron-darkened water--has been discovered at 8,500-foot depths by an expedition funded by the National Science Foundation (NSF) to explore the Pacific Ocean floor off Costa Rica.

[Monday, April 23, 2007] A spectacular fossilised forest has transformed our understanding of the ecology of the Earth’s first rainforests. It is 300 million years old.

[Tuesday, April 24, 2007] Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water.

[Tuesday, April 24, 2007] Plants have been to space since 1960, but NASA's plant growth experiments began in earnest during the 1990s. Experiments aboard the space shuttle and International Space Station have exposed plants to the effects of microgravity.

[Thursday, April 26, 2007] Earth sits between two worlds that have been devastated by climate catastrophes. In the effort to combat global warming, our neighbours can provide valuable insights into the way climate catastrophes affect planets.

[Saturday, April 28, 2007] On Wednesday, April 25, the National Science Foundation (NSF) Web site will debut a new, fully illustrated, multimedia Special Report describing research on strange organisms that can live in ferocious extremes of cold, heat, pressure, acidity and more.
