Astronomers have long sought strong evidence that Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, is producing a jet of high-energy particles. Finally they have found it, in new results from NASA's Chandra X-ray Observatory and the National Science Foundation's Very Large Array (VLA) radio telescope.
Doom may be averted for the Smith Cloud, a gigantic streamer of hydrogen gas that is on a collision course with the Milky Way Galaxy. Astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) and Robert C. Byrd Green Bank Telescope (GBT) have discovered a magnetic field deep in the cloud’s interior, which may protect it during its meteoric plunge into the disk of our Galaxy.
Researchers using NASA’s Chandra X-ray Observatory have found evidence that the normally dim region very close to the supermassive black hole at the center of the Milky Way Galaxy flared up with at least two luminous outbursts in the past few hundred years.
For the first time, astronomers have seen the image of a distant quasar split into multiple images by the effects of a cloud of ionized gas in our own Milky Way Galaxy. Such events were predicted as early as 1970, but the first evidence for one now has come from the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope system.
Astronomers used the new ALMA (Atacama Large Millimetre/submillimetre Array) telescope in Chile – the most powerful radio telescope in the world – to view the stellar womb which, at 500 times the mass of the Sun and many times more luminous, is the largest ever seen in our galaxy.
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors.
Our very own Milky Way is likely a spiral galaxy. Indeed, our solar system and Earth reside somewhere near one of its filamentous, swept-back arms.
Astronomers are observing a black hole that woke up from a decades-long slumber to feed on a low-mass object - either a brown dwarf or a giant planet - that strayed too close.
The Universe is a considerably old neighbourhood, weighing in at approximately 13.8 billion years old. Our galaxy, the Milky Way, is also ancient - as some of its stars are more than 13 billion years old.
While performing an extensive X-ray survey of our galaxy's central regions, NASA's Swift satellite spotted the previously unknown remains of a shattered star.
There's probably an Earth-sized planet with a comfortable temperature as little as 13 light years away, data from NASA’s Kepler space telescope implies.
The ancient Egyptians associated the dung beetle with the sun, seeing a parallel between the way it rolls its ball of dung and the way the sun moves across the sky.
The Large Magellanic Cloud, a satellite galaxy of the Milky Way, floats in space nearly 200,000 light-years from Earth in a long and slow dance around our galaxy.
A rather busy patch of space was recently snapped by NASA's Hubble Space Telescope. Scattered with many nearby stars, the field boasts numerous galaxies in the background.
Astronomers have identified a new part of our Milky Way galaxy; a structure they are calling the 'bone'.
Using the Sloan Digital Sky Survey, researchers have discovered a stream of stars believed to be the remnant of an ancient cluster slowly being ingested by our own Milky Way galaxy.
An international team of astronomers has created a catalogue of more than 84 million stars in the central parts of the Milky Way using a 9-gigapixel image from the VISTA infrared survey telescope.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has taken its first look at the giant black hole at the center of our galaxy - and caught it right in the middle of a flare-up.
NASA's Swift satellite recently detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy.
Our Milky Way Galaxy is surrounded by an enormous halo of hot gas hundreds of thousands of light years across, and with as much mass as all the stars in the galaxy.
