Hubble Telescope Discovers New Dwarf Spheroidal Galaxy In Our Cosmic Backyard

Let's welcome our new galactic neighbor, Bedin 1.

It seems like astronomers discovered yet another galaxy in our galactic neighborhood. A mysterious galaxy hiding behind the cluster, distant undiscovered galaxy millions of light-years away. Interestingly, the new galaxy was discovered by accident by the Hubble space telescope.

While investigating a nearby globular star cluster called NGC 6752, a team of astronomers stumbled upon the brand new galaxy, designated Bedin 1.

According to NASA:


The Hubble Space Telescope (HST) was NASA's project in collaboration with the European Space Agency (ESA). HST, for those whose don't already know, is a space telescope which was launched 1990 and still in operation in low Earth orbit to date.

Bedin 1 is a very old dwarf spheroidal galaxy, possibly as old as 13 billion years. This also puts Bedin 1 at about the very age of the universe itself. Additionally, the diminutive Bedin 1 galaxy is only about 3,000 light-years across. In comparison with our Milky Way, Bedin 1 is about 30 times smaller and around a thousand times dimmer.

The new galaxy is also very isolated from other galaxies. According to astronomers, Bedin 1 is the most distant standalone dwarf galaxy yet discovered so far.

As per the European Space Agency, the discovery of Bedin 1 was a delightful accident as the Hubble space telescope is rarely captured such images, especially for a dim object which covers only a small section of the sky.

The findings have been now published on January 21, 2019, by the Monthly Notices of the Royal Astronomical Society: Letters.
