Time and tide wait for no man. So the XMM-Newton space telescope is making every second count. As the telescope shifts its gaze from source to source, it's recording the X-ray sky.
Astronomers around the world are watching as the gaseous object called G2 heads for a close pass around the Milky Way's central supermassive black hole. Now it looks like the distended cloud is starting to swing back toward us.
The Cat's Paw Nebula is home to many bright, young stars. But thousands of fainter stars concealed behind dust reveal themselves in a new infrared image.
Astronomers have been waiting for our galaxy’s slumbering supermassive black hole to stir for a snack. Instead, the universe handed them a different treat.
Observations of Milky Way’s chaotic center show hints of stars forming just two light-years away from our galaxy’s supermassive black hole.
Astronomers investigating a supernova remnant see nothing but swirls of gas. The lack of stellar remains means the explosion must have birthed a black hole only 1,000 years ago.
New observations of spaghetti-thin clouds, faraway star-forming regions and mysterious magnetic fields are revealing the hard-to-see structure of the galaxy we call home.
New microwave and radio observations resurrect controversy over gigantic lobes seen ballooning from the Milky Way’s center.
Astronomers have discovered an unexpected explanation for why they can only find a small fraction of the satellite galaxies the Milky Way is supposed to have.
Our galaxy’s central supermassive black hole emits regular, mysterious X-ray flares. For the first time, NASA’s newest sharp-eyed telescope has captured a high-energy view of the action.
The Orion Nebula hosts a well studied star cluster, the gold standard by which astronomers measure all other clusters. New research suggests that this benchmark might need to be revised.
Astronomers announced that they've successfully tracked a star that takes less than 12 years to whip around the Milky Way's central black hole. The star isn't so special on its own, but combined with other observations it might help unwrap the region's mysteries.
New radio observations suggest that one of the brightest globular clusters in the sky, Messier 22, hosts two stellar mass black holes.
The Orion Nebula Cluster might be home to a black hole more than 100 times the mass of the Sun, according to a recent simulation.
A careful analysis of Planck observations shows that there really is a mysterious haze emanating from the Milky Way’s core, mission team members say.
A collaboration between professional and amateur astronomers is producing a careful map of stellar brightnesses and colors across the entire night sky. The survey should fill a hole that sometimes hampers quick, accurate measurements of events such as supernovae.
Astronomers hunting for brown dwarfs in our solar neighborhood have been thrown a surprise: these star wannabes are far less common than previously thought.
If anyone's still around 4 billion years from now, they'll have a ringside seat for a true clash of titans, as the Milky Way and Andromeda galaxies smash into each other and merge.
In just 10 months during 2010, an orbiting observatory meticulously recorded a "heat map" of the entire celestial sphere, revealing unseen beauty in the Milky Way and providing astronomers with a catalog of more than a half billion celestial objects.
A new analysis suggests that "nomad" planets, ejected from their home stellar systems and now adrift in the icy dark of interstellar space., could outnumber stars by as many as 100,000 to 1.
Observations of a black hole that spat out twin blobs of superhot material may help astronomers understand how the mysterious beasts create powerful jets that shoot out from their poles. The blobs appeared just as the system went quiet in X-rays.
Astronomers have discovered a dusty, stretched-out cloud heading for the supermassive black hole lurking in the Milky Way's core. The blob could be the meal the beast needs to wake up for a bit from its slumber, if the cloud survives its incoming trip on the dining cart.
Recent gamma-ray observations support the longstanding theory that superspeedy particles called cosmic rays have their origin in the havoc-ridden regions around young star clusters.
Astronomers have pinned down the distance, mass, and spin rate for the first black hole candidate discovered, information that points to a birth sans supernova.
Some deceptively youthful stars may find their fountains of youth in material they grab off other stars.
