Supernova explosions and the jets of a monstrous black hole are scattering a galaxy’s star-making gas like a cosmic leaf blower, a new study finds. The findings, which relied on ultraviolet observations from NASA’s Galaxy Evolution Explorer and a host of other instruments, fill an important gap in the current understanding of galactic evolution.


Time is running out for the …

Studies using X-ray and ultraviolet observations from NASA’s Swift satellite provide new insights into the elusive origins of an important class of exploding star called Type Ia supernovae.


Three types of systems, illustrated here, may host Type Ia supernovae. The first two panels depict a white dwarf in a binary system accumulating matter transferred from a red supergiant companion many …

The human eye is crucial to astronomy. Without the ability to see, the luminous universe of stars, planets and galaxies would be closed to us, unknown forever. Nevertheless, astronomers cannot shake their fascination with the invisible.

Outside the realm of human vision is an entire electromagnetic spectrum of wonders. Each type of light–­from radio waves to gamma-rays–reveals something unique about …

NASA unveiled a new atlas and catalog of the entire infrared sky today showing more than a half billion stars, galaxies and other objects captured by the Wide-field Infrared Survey Explorer (WISE) mission.


This is a mosaic of the images covering the entire sky as observed by the Wide-field Infrared Survey Explorer (WISE), part of its All-Sky Data Release. Image …

Astronomers using data from NASA’s Hubble Telescope have observed what appears to be a clump of dark matter left behind from a wreck between massive clusters of galaxies. The result could challenge current theories about dark matter that predict galaxies should be anchored to the invisible substance even during the shock of a collision.


This composite image shows the distribution …

Astronomers using ESA’s Herschel and NASA’s Spitzer space telescopes have detected surprisingly rapid changes in the brightness of embryonic stars within the well-known Orion Nebula.


This new view of the Orion Nebula shows embryonic stars within extensive gas and dust clouds. Combining far-infrared observations from the Herschel Space Observatory and mid-infrared observations from NASA’s Spitzer Space Telescope, the image shows …

ESA’s Planck mission has revealed that our Galaxy contains previously undiscovered islands of cold gas and a mysterious haze of microwaves. These results give scientists new treasure to mine and take them closer to revealing the blueprint of cosmic structure.


This all-sky image shows the distribution of carbon monoxide (CO), a molecule used by astronomers to trace molecular clouds across …

In 1995, the Hubble Space Telescope’s ‘Pillars of Creation’ image of the Eagle Nebula became one of the most iconic images of the 20th century. Now, two of ESA’s orbiting observatories have shed new light on this enigmatic star-forming region.


Combining almost opposite ends of the electromagnetic spectrum, this composite of the Herschel in far-infrared and XMM-Newton’s X-ray images shows …

The High Frequency Instrument on ESA’s Planck mission has completed its survey of the remnant light from the Big Bang. The sensor ran out of coolant on Saturday as expected, ending its ability to detect this faint energy.

“Planck has been a wonderful mission; spacecraft and instruments have been performing outstandingly well, creating a treasure trove of scientific data for …
