Astronomers Spot Stars Soaring Out of the Galaxy

Astronomers this week revealed that they have discovered a new type of star traveling fast enough to leave the Milky Way galaxy. The stars, dubbed “hypervelocity stars,” are different than other stars found traveling at such speeds as they did not come from the center of the galaxy. “These new hypervelocity stars are very different from the ones that have …

Astronomers Confirm Milky Way Particle Jet

Astronomers this week have revealed the confirmation that the black hole at the center of our galaxy is ejecting a stream of high-energy particles. The new findings have been published in The Astrophysical Journal. Researchers for some time have assumed that our Milky Way galaxy has a jet of particles spouting from its center, much like other galaxies similar to …

8.8 Billion Earth-Like Planets Inhabit the Milky Way

The AP via NBC News took notice of a study published this week in the Proceedings of the National Academy of Sciences: apparently, Earth is one of 8.8 billion similar planets in the Milky Way that fall inside the “Goldilocks zone,” the area around a sun where a planet’s orbit is neither too hot nor too cold for life. A …

Milky Way Galaxy “Geysers” Spotted

A team of astronomers has detected detected huge outflows of charged particles streaming out of the center of our galaxy, the Milky Way. The outflows were detected using the CSIRO’s Parkes radio telescope in Australia, and the new research has been published today in the journal Nature. “These outflows contain an extraordinary amount of energy – about a million times …

NASA Spots Milky Way Black Hole “Flare-Up”

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has taken its first images of the giant black hole at the center of our galaxy and caught it in the middle of a “flare-up.” “We got lucky to have captured an outburst from the black hole during our observing campaign,” said Fiona Harrison, the mission’s principal investigator at the California Institute of Technology. …

Milky Way is Surrounded by Hot Gas, Says NASA

Astronomers at NASA’s Chandra X-ray Observatory have found evidence that the Milky Way galaxy is surrounded by a halo of hot gas. Extending for hundreds of thousands of light years, the mass of the gas cloud is estimated to be comparable to the mass of all the stars in the galaxy. “Our work shows that, for reasonable values of parameters …

NASA Reveals Milky Way Will Collide With Andromeda

Using sophisticated math and the Hubble telescope, NASA has determined that the Milky Way and the Andromeda galaxies are on a collision course…..in 4 billion years. Computer simulations taken from Hubble’s data show that it will take an additional two billion years after the collision for the two galaxies to completely merge and reshape into a single elliptical galaxy. “In …

Billions Of Inhabitable Planets Found In Milky Way

People have wondered aloud for decades that if our planet one day became uninhabitable, would we be able to find a new home? Well until recently scientists had hypothesized that there were at most a couple thousand inhabitable planets in our galaxy. Now it has come to light in a recent discovery that there are more like billions of planets …
