The Milky Way once had a large sister galaxy — but Andromeda devoured it

Astronomers unravel a gruesome galactic murder… and we might be next!

Two billion years ago, Andromeda ‘ate’ a sister-galaxy of the Milky Way

The findings could topple our current understanding of how galaxies merge.

Scientists just found the first relic galaxy — it’s remained unchanged since the early universe

A breakthrough moment in astronomy.

Researchers map out the age of the Milky Way’s “heart”

Our galaxy still holds many secrets.

Ginormous hydrogen clouds whizz around the Milky Way at phenomenal speeds

Scientists gain new insight into mysterious cloud formations traveling around the galaxy.

The Milky Way might not be your typical spiral galaxy but is it unique?

The Milky Way just got an ego boost.

Researchers find tantalizing evidence of mid-sized black hole in the Milky Way

If confirmed, this could indicate a remarkable progress in modern physics.

Researchers spot the biggest brown dwarf ever, trailing at the edge of the Milky Way

Surprisingly pure.

Two dwarf-galaxies have left the wilderness to join a galactic party

Drawn by gravity, a dwarf galaxy pair is leaving the void for a more crowded region of the universe.

Scientists uncover unique speed and direction of Milky Way’s spinning ‘halo’

The findings could reveal the location of the missing matter of our universe.

NASA’s Kepler Space Telescope discovers 104 new planets outside of Milky Way

Of these planets, four are believed to potentially be similar to Earth.

Lonely planet is actually part of the largest planetary system in the Milky Way

Astronomers find the parent of an orphan planet. The finding makes the solar system the biggest in the galaxy.

First ‘growth chart’ developed for the Milky Way

The Milky Way has been around for at least 13.7 billion years, but it has its younger and older areas.

Biggest space picture ever: a 46 billion megapixel view of the Milky Way

After five years of painstakingly stitching together pictures of the Milky Way, astronomers from Ruhr University Bochum have finally completed their masterpiece: the largest ever space photo. It has a whooping 46 billion megapixel and 194 GB in file size. It’s so large, in fact, that the astronomers had to cut it in 268 sections for it be manageable.

Milky Way Galaxy May be Way Larger Than Previously Thought

It is generally accepted that our galaxy has a diameter of nearly 100,000 light-years. However, findings of a new research, published in the Astrophysical Journal, suggest that the Milky Way may actually be 50% larger than previously thought. The Milky Way is a spiral galaxy containing our solar system. From Earth, the Milky Way appears as a band because its disk-shaped structure

Our Galaxy Might Be a Huge Wormhole

Based on latest evidence and calculations, our entire galaxy, the Milky Way, might be a a huge wormhole, stable and navigable. Astrophysicists combined the equations from general relativity with a distribution of dark matter to reach this conclusion

Astronomers map the Supercluster the Milky Way belongs to

Our sun is but a tiny speck of light among billions, part of the spiral galaxy we familiarly call the Milky Way. That in itself makes us puny humans feel extremely humble, but things get really out of proportion when you zoom out. Galaxies on their own turn congregate in the hundreds or even thousands, bound together by gravity to

Astronomers find the sun’s first sibling: a star made of the same stuff

In what’s considered the first find out of a slew to follow, a team of astronomers have identified a star that originated out of the same matter as our own sun. In lack of a better analogy, the two are siblings and probably share many more sisters. Apart from telling us where in the galaxy our solar system first formed

Star surveyor Gaia enters its operational orbit

The European Space Agency‘s billion-dollar star surveyor ‘Gaia’ is now in its operational orbit around a gravitationally stable virtual point in space, at about 1.5 million km from Earth. Gaia has been traveling to reach that point since December 19, following a spectacular launch from Europe’s Spaceport in Kourou, French Guiana. Last night, the surveyor performed the last critical maneuvers,

The Milky Way grows back two spiral arms

There has been a debate over the number of spiral arms the Milky Way galaxies has, due to mixed results in the past. For years, it was believed the Milky Way had four spiral arms, but in 2008 readings from the Spitzer Space Telescope suggested it actually had only two. Wouldn’t you know it, a new study that looked at
