Gamma-Ray Sky around the Blazar PKS B1424-418
Nearly 10 billion years ago in a galaxy known as PKS B1424-418, a dramatic explosion occurred.
On 26 April 2016 ESO's Paranal Observatory in Chile hosted an event to mark the first light for the four powerful lasers that form a crucial part of the adaptive optics systems on ESO's Very Large Telescope.
NASA engineers recently unveiled the giant golden mirror of NASA's James Webb Space Telescope as part of the integration and testing of the infrared telescope.
France's Microscope satellite, carrying a set of ESA high-tech thrusters, lifted off last night from Europe's Spaceport in Kourou, French Guiana, taking advantage of the same Soyuz launch that took the EU's Sentinel-1B into orbit.
The elegant simplicity of NGC 4111, seen here in this image from the NASA/ESA Hubble Space Telescope, hides a more violent history than you might think.
ESA's Herschel mission releases today a series of unprecedented maps of star-forming hubs in the plane of our Milky Way galaxy.
For the 26th birthday of NASA's Hubble Space Telescope, astronomers are highlighting a Hubble image of an enormous bubble being blown into space by a super-hot, massive star.
HAWC observations show that a previously known gamma ray source in the Milky Way galaxy, TeV J1930+188, which is probably due to a pulsar wind nebula, is far more complicated than originally thought.
On Sept. 14, waves of energy traveling for more than a billion years gently rattled space-time in the vicinity of Earth.
At first glance, this NASA/ESA Hubble Space Telescope image seems to show an array of different cosmic objects, but the speckling of stars shown here actually forms a single body a nearby dwarf galaxy known as Leo A.
Subtle distortions hidden in ALMA's stunning image of the gravitational lens SDP.81 are telltale signs that a dwarf dark galaxy is lurking in the halo of a much larger galaxy nearly 4 billion light-years away.
Galaxies, it seems, are sociable animals and they like to gather together in large groups, known as clusters.
The star HD 44179 is surrounded by an extraordinary structure known as the Red Rectangle. It acquired its moniker because of its shape and its apparent color when seen in early images from Earth.
Astronomers have uncovered a near-record-breaking supermassive black hole, weighing 17 billion suns, in an unlikely place: in the center of a galaxy in a sparsely populated area of the universe.
Last February a team of astronomers reported detecting an afterglow from a mysterious event called a fast radio burst, which would pinpoint the precise position of the burst's origin, a longstanding goal in studies of these mysterious events.
Peering deep into the dusty heart of our Milky Way galaxy using infrared vision, NASA's Hubble Space Telescope reveals a rich tapestry of more than half a million stars.
Star formation is taking place all around us. The Milky Way is laced with clouds of dust and gas that could become the nursery of the next generation of stars
