New Organic Compounds Found in Enceladus Ice Grains

In this image captured by NASA’s Cassini spacecraft in 2007, the plumes of Enceladus are clearly visible. The moon is nearly in front of the Sun from Cassini’s viewpoint.

New kinds of organic compounds, the ingredients of amino acids, have been detected in the plumes bursting from Saturn’s moon Enceladus. The findings are the result of the ongoing deep dive into data from NASA’s Cassini mission.Powerful hydrothermal vents eject material from Enceladus’ core, which mixes with water from the

NASA lab brews up alien atmospheres here on Earth

A NASA team has recreated the atmosphere of a "hot Jupiter" exoplanet, similar to this artist's rendition of WASP-18b

Earth's pleasant, life-giving atmosphere is turning out to be somewhat of an oddity. With almost 4,000 planets so far discovered orbiting stars beyond our solar system, scientists are finding that atmospheres come in a wide range of recipes. To get a better understanding of that cosmic chemistry, a team at

Decade long study sheds light on “killer” galactic mergers

Two merging galaxies known as Arp 302, also called VV 340

Images taken by NASA's Spitzer Space Telescope are providing insight into the phenomenon of "killer" galaxies that, when they merge, shut down star formation within the new united galaxies. The collision and mixing of a pair of galaxies under the right (or wrong) conditions can disrupt the processes that allow

NASA to Make Announcement About Kepler Telescope

An illustration of the Kepler space telescope.

NASA is about to make an announcement about the Kepler, potentially to say the planet-hunting telescope has finally run out of fuel almost a decade after being launched into space.A tweet from the agency that in the teleconference, it will “provide an update on the status” of the telescope, and

NASA Voyager 2 could be nearing interstellar space

This graphic shows the position of the Voyager 1 and Voyager 2 probes relative to the heliosphere, a protective bubble created by the Sun that extends well past the orbit of Pluto. Voyager 1 crossed the heliopause, or the edge of the heliosphere, in 2012. Voyager 2 is still in the heliosheath, or the outermost part of the heliosphere.

NASA's Voyager 2 probe, currently on a journey toward interstellar space, has detected an increase in cosmic rays that originate outside our solar system. Launched in 1977, Voyager 2 is a little less than 11 billion miles (about 17.7 billion kilometers) from Earth, or more than 118 times the distance

Last gasp? NASA fires up fading Kepler telescope for Campaign 19

Kepler's fuel stocks are dwindling, but there may be life left in it yet

Although the science mission of its successor, the Transiting Exoplanet Survey Satellite (TESS), is now underway, NASA isn't done with the Kepler Space Telescope just yet. Its scientists have awoken the deep space probe to gather scientific data yet again, though with an unknown amount of fuel and a compromised
