The Galaxy Next Door
At approximately 2.5 million light-years away, the Andromeda galaxy is our Milky Way's largest galactic neighbor. The entire galaxy spans 260,000 light-years across -- a distance so large, it took 11 different Galaxy Evolution Explorer image segments stitched together to produce this view of the galaxy next door.

New results from NASA's NEOWISE survey find that more potentially hazardous asteroids, or PHAs, are closely aligned with the plane of our solar system than previous models suggested. .

Russia's spacecraft Soyuz TMA-04M with a crew of three blasted off from the Baikonur space center in Kazakhstan on Tuesday, according to Russia's Federal Space Agency Roscosmos.

Technicians prep the OCO-2 instrument for shipping at JPL. The instrument consists of three parallel, high-resolution spectrometers, integrated into a common structure and fed by a common telescope.

Mineral Diversity at Vesta's South Pole
This image, made from data obtained by NASA's Dawn spacecraft, shows the mineral distribution in the southern hemisphere of the giant asteroid Vesta.

A collaboration between a scientist and a designer from Africa has resulted in the creation of a fashionable hooded bodysuit embedded at the molecular level with insecticides for warding off mosquitoes infected with malaria.

This artistically modified image of the local galaxy Arp 220, captured by the Hubble Space Telescope, helps illustrate the Herschel results.

NASA's Spitzer Space Telescope was able to detect a super Earth's direct light for the first time using its sensitive heat-seeking infrared vision.

The space-based technology that lets GPS-equipped motorists constantly update their precise location will undergo a major test of its ability to rapidly pinpoint the location and magnitude of strong earthquakes across the western United States. Results from the new Real-time Earthquake Analysis for Disaster (READI) Mitigation Network soon could be used to assist prompt disaster response and more accurate tsunami warnings.

It's a dust bunny of cosmic proportions. Astronomers used images from NASA's Wide-field Infrared Survey Explorer, or WISE, to locate an aging star shedding loads of dust (orange dot at upper left). Only one other star, called Sakurai's object, has been caught erupting with such large amounts of dust. The process is a natural part of aging for stars like our sun. As they puff up into red giants, they shed dust that is later recycled back into other stars, planets, and in the case of our solar system, living creatures.
