Astronomers Create Most Detailed Weather Map Yet of an Exoplanet

Being able to find exoplanets orbiting distant stars is a major accomplishment in itself, and fine-tuning the data [...]

Mission to Jupiter: 25 Years Since the Launch of Galileo (Part 1)

Emblazoned with the script-like “Galileo” lettering and the block “NASA” letters, the spacecraft represented a marriage of romance and adventure with science and technology for STS-34’s Shannon Lucid. Photo Credit: NASA

When the Galileo spacecraft drifted out of Shuttle Atlantis’ payload bay on the evening of 18 October 1989—25 years ago, next week—on the [...]

Plate Tectonics May Increase Chances for Life on Europa

Europa, with its subsurface ocean, and now evidence for plate tectonics, is a primary goal of exploration in the search for alien life. Processed image copyright: Ted Stryk. Image Credit: NASA/JPL-Caltech/Ted Stryk

Jupiter’s moon Europa is a fascinating little world, but particularly so for one reason: water. It’s deep alien ocean underneath the surface [...]

Living On the Edge: The Inviting Waters of Europa (Part 2)

Jupiter’s moon Europa, as seen by NASA’s Galileo spacecraft. A long line of evidence has shown that Europa has an underground ocean of liquid water, which for many scientists constitutes the best place in the Solar System to search for alien life. Image Credit: NASA/JPL/Ted Stryk

“Since ’tis certain that Earth and Jupiter have [...]

A Troubled Start to a Triumphant Mission: 37 Years Since the Launch of the Voyagers

Voyager 2 begins its journey of exploration, 37 years ago today (20 August), with a rousing liftoff atop a Titan IIIE-Centaur booster from Launch Complex (LC)-41 at Cape Canaveral. Photo Credit: NASA

A quarter-century ago, this week, NASA’s Voyager 2 spacecraft became the first machine fashioned by human hands to travel close to the [...]

It’s three down and two to go for NASA’s Jupiter-bound Juno probe, which marks a major milestone today, Aug. 5, celebrating its launch exactly three years ago—on Aug. 5, 2011—from Cape Canaveral Air Force Station, Fla., on a journey to discover [...]

No Water, Please: The Case of the Surprisingly Dry 'Hot Jupiters'

This is an artistic illustration of the gas giant planet HD 209458b in the constellation Pegasus. The planet was recently studied by astronomers alongside two other similar extrasolar worlds, for their abundance in water. To the surprise of astronomers, they have found much less water vapor in the planets’ atmospheres than standard planet-formation models [...]

Titan's Hidden Ocean Might Be as Salty as the Dead Sea

Saturn’s moon Titan is known for its methane seas, lakes, and rivers; surprisingly Earth-like in appearance yet distinctly alien at the same time. But there is also evidence for another [...]

As the number of exoplanets discovered continues to grow exponentially, the number of potentially habitable worlds out there continues to increase as well. Astronomers have now reported finding another one of the nearest known of these kinds of planets so far, Gliese [...]

Colorful Hubble Image Provides Missing Link Concerning Star Formation

This composite image from the Hubble Space Telescope (HST) showing approximately 10,000 galaxies in brilliant color took nine years to assemble, and sheds light upon star formation in our Universe. Image Credit: NASA/ESA

NASA and the European Space Agency’s Hubble Space Telescope (HST) has done it again—this time, in brilliant color. A newly released [...]
