Astronomers Find a Galaxy Free of Dark Matter

This is the first time astronomers find an entire galaxy that’s devoid of dark matter. A poorly-understood building block of our universe. Astronomers on Wednesday (March 28) announced the discovery of the first and only known galaxy without dark matter. Astronomers think that dark matter makes up about 27 percent of our...

Astronomers Discover that all Galaxies Spin the Same

Recently, astronomers have discovered that no matter how big, all galaxies rotate once every billion years. Researchers think this is weird. Lead researcher Gerhardt Meurer said the discovery was “kind of weird.” “I just thought that’s kind of odd, small galaxies and big galaxies all orbiting at the same...

Hubble Caught a Stunning Photo of Cartwheel Galaxy

NASA/ESA’s (European Space Agency) Hubble Space Telescope captured an amazing view of the Cartwheel Galaxy. A violent galactic collision reshaped it. About 100 million years ago, a smaller galaxy has passed right through a large disk galaxy. Thus, producing shock waves that swept up gas and dust – much like the...

Astronomers Discover Supermassive Black Hole that “Burps”

Supermassive black holes reside at the center of most, if not all, massive galaxies. Astronomers recently discovered a supermassive black hole that “burps”. It lies approximately 900 million light-years from Earth, in a galaxy called SDSS J1354+1327 (J1354 for short). The work, presented at the Washington, D.C.,...

This Is How Earth And The Solar System Are Moving Through Space

We live in our lovely home, Earth, which spins on its axis and revolves around the Sun. Our star orbits in an ellipse around the center of the Milky Way and everything is moving through space. The Milky Way is on a collision course with another galaxy. Our galaxy is being pulled towards the Andromeda within our local group. The...

Earth And Its Parent Galaxy Live In A Cosmic Void

According to a study, we live in a cosmic void, which is a region of space largely devoid of other galaxies, stars, and planets. If our universe were a sponge, the milky way would dwell in one of the spongy holes. These cosmic voids are part of the large-scale structure of the universe. Once scientists thought that Earth was...

Large Magellanic Cloud: A Galaxy Within A Galaxy

The Large Magellanic Cloud is a satellite galaxy of the Milky Way nearly 200,000 light-years from Earth. The LMC is the third closest galaxy to the Milky Way. In fact the galaxy is thought to be orbiting inside the Milky Way. Vast clouds of gas within it slowly collapse to form new stars. From the Tarantula Nebula, the...

What Happens When Galaxies Collide With Each Other

Interactions between galaxies are quite normal, especially between giant and satellite galaxies. Two galaxies are drawn together by forces they can’t see but they can feel. It’s a mutual gravitational attraction. Because of this, galaxies come too close to one another, to the point where the gravity of the...

What Are Satellite Galaxies?

Our sun is one of a massive collection of stars in the Milky Way galaxy, while every star orbits the center of the galaxy. But these hundreds of billions of stars are not the only big things orbiting the center of the galaxy. A whole galaxy can orbit the center of another bigger galaxy. Astronomers call these kinds of...

Learn What Lies Beyond Our Solar System

Our sun is not the only one in the Galaxy. There are at least 100 billion stars beyond our solar system, a spiral galaxy about 100,000 light-years across. Our star along with its planets float around the milky way galaxy. Stars beyond our Solar System are arranged in a pinwheel pattern with four major arms, and we live about...
