Researchers Give Guideline for Future Alien Life Search

Using an altitude-dependent photochemical model with the enhanced lower boundary conditions necessary to carefully explore abiotic oxygen and ozone production on lifeless planets with a wide variety of volcanic gas fluxes and stellar energy distributions, scientists at NASA have developed new guidelines for the search for life on other planets. Astronomers searching the atmospheres of […]

Astronomers View Massive Galaxy in Core Formation Phase

By combining observations from several telescopes, astronomers have viewed a massive galaxy in its core formation phase three billion years after the Big Bang. Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a dense galactic core blazing with the light […]

Image of Neptune from Voyager 2

This historic image of Neptune was taken twenty-five years ago by NASA’s Voyager 2 Spacecraft. NASA’s Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on […]

New Mars Image Shows Rolling Boulder

A newly released image from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter shows an irregularly shaped boulder that apparently rolled down a hill on Mars and stopped in an upright position. A track about one-third of a mile (500 meters) long on Mars shows where an irregularly shaped boulder careened downhill to its current […]

Curiosity Rover Nears Mountain Base Outcrop

NASA’s Mars Curiosity rover is approaching its first close look at bedrock that is part of Mount Sharp, approaching a geological unit that’s part of the base of the mountain rather than the floor of the crater. As it approaches the second anniversary of its landing on Mars, NASA’s Curiosity rover is also approaching its […]

NASA Detects Best Evidence Yet For Coronal Heating Theory

NASA’s EUNIS sounding rocket mission has discovered evidence to explain why the sun’s atmosphere is so much hotter than its surface, detecting the strongest evidence yet for the presence of nanoflares. Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun’s outer atmosphere so much hotter than its […]

Cassini Reveals 101 Geysers on Enceladus

Using data from NASA’s Cassini spacecraft, two newly published studies detail the discovery of 101 distinct geysers on Saturn’s icy moon Enceladus. Scientists using mission data from NASA’s Cassini spacecraft have identified 101 distinct geysers erupting on Saturn’s icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon’s […]

New Views of the Rosetta Comet

New images from ESA’s Rosetta spacecraft reveal surface structures of comet 67P/Churyumov-Gerasimenko, allowing scientists to create a 3D shape model of the nucleus. As the European Space Agency’s Rosetta probe approaches Comet 67P/Churyumov-Gerasimenko (67P) for an August rendezvous, the comet’s core is coming into sharper focus. Today, ESA released a new set of images and […]
