Not long ago, the center of the Milky Way exploded

A titanic, expanding beam of energy sprang from close to the supermassive black hole in the center of the Milky Way just 3.5 million years ago, sending a cone-shaped burst of radiation through both poles of the galaxy and out into deep space.

Milky Way's Black Hole Has Grown 75 Times as Bright for a Few Hours

Observing Sagitarius A ( a supermassive balck hole in the center of our galaxy ) with the Keck's telescope, scientists just watched as its brightness bloomed to over 75 times normal for a few hours. Astronomers aren’t certain what caused the flaring. 

New Visualization Provides Ultra HD View of Our Galaxy Center

This 360-movie offers an unparalleled opportunity to look around the center of the galaxy, from the vantage point of the central supermassive black hole, in any direction the user chooses.

Milky Way tips the scales at 1.5 trillion solar masses

Using ESA's Gaia spacecraft and NASA’s Hubble Space Telescope, astronomers have come up with the most accurate measurement yet of the Milky Way’s total mass. It contains about 1.5 trillion times the mass of Earth’s Sun.

Intermediate mass black hole found near galactic centre

The “quiet” black hole is located just 20 light years from the supermassive four-million-solar-mass black hole lurking at the centre of the Milky Way. In the future, it will fall into the supermassive black hole.

Astronomers Discover Three New Globular Clusters in Milky Way

A duo of astronomers has spotted three new globular clusters in the Milky Way’s bulge, a 10,000-light-year-wide central structure made primarily of old stars, gas and dust.

The Milky Way Devoured Another Galaxy 10 Billion Years Ago

More precisely, the Milky Way collided with the second galaxy, absorbing many of its stars and spiraling out a chaotic tangle of stellar matter — birthing new stars and altering the orbits of others.

The Milky Way Could Be Spreading Life From Star to Star

According to the model of US researchers, the entire Milky Way (and even other galaxies) could be exchanging the components necessary for life.

Gamma rays seen from exotic Milky Way object

For the first time, an international collaboration of scientists has detected highly energetic light coming from the outermost regions of an unusual star system within our own galaxy.

Astronomers stunned by Eta Carinae – the star that will not die

About 170 years ago, Eta Carinae erupted with a titanic blast becoming at one point the second brightest star in the night sky. Somehow, the star survived the “Great Eruption”, providing an intriguing mystery for astronomers.

Einstein's general relativity confirmed near black hole

Observations have for the first time clearly revealed the effects of Einstein's general relativity on the motion of a star passing through the extreme gravitational field very close to the supermassive black hole.

New South African Telescope Releases Epic Image of the Galactic Center

You’re looking at the center of our galactic home, the Milky Way, as imaged by 64 radio telescopes in the South African wilderness.

Mystery objects whizzing about in Milky Way’s core

Spectroscopic measurements of gas dynamics at the core of the Milky Way have revealed several unusual objects visibly whizzing around the supermassive black hole at the center of the galaxy .

Stellar mass black holes swarm in Milky Way’s core

The Chandra Observatory has found direct evidence for up to 10 stellar-mass black holes and thousands more lurking within a few light years of Sagittarius A*, the supermassive black hole at the center of the Milky Way.

A Hidden Galaxy Has Been Found Orbiting Our Milky Way

Scientists have found what looks like an exceedingly small galaxy in orbit around our Milky Way. Named Hydrus 1, it’s located about 90,000 light-years from Earth, between the Small and Large Magellanic Clouds.
