Oldest Galaxy Record May be broken (Again)

Oldest Galaxy Record May be broken (Again)

Hubble appears to have beaten the record for the oldest galaxy observed by over 120Million light years. While there may  be some confirmation to do on the discovery , the candidate Galaxy named UDFj-39546284, is seen as it was just 480 million years after the Big Bang at a distance of 13.2 billion light years away. Current theory suggests we [...]

The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted [...]

M31-Milky Way simulated collision

M31-Milky Way simulated collision

 It may be a few billion years away(about 4.5), but it is believed that the two largest galaxies in our local group will merge.   The radial velocity of the Andromeda galaxy with respect to the Milky Way can be measured by examining the Doppler shift of spectral lines from stars in the galaxy, but the transverse velocity cannot be directly [...]
