The object is thought to be the missing link between planets and stars, with a mass up to 80 times that of Jupiter
Astronomers using the Hubble Space Telescope have performed an accurate census of the number of galaxies in the cosmos
The finding means we can now classify these structures according to their physical properties rather than human interpretation
A new infrared image from NASA’s Spitzer Space Telescope may remind fans of the TV series
NGC 4833, captured in all its glory, is one of over 150 globular clusters known to reside within the Milky Way
Astronomers have obtained the most precise measurement yet of how fast the universe is expanding at the present time
We have the answer to this intriguing question
A previously unknown link between the way young stellar objects grow and the way black holes feast on their surroundings has been discovered
This stunning image, taken by the Hubble Space Telescope, shows the individual galaxies UGC 1810 (right) and UGC 1813 (left) in the process of colliding. Together, this pair of interacting galaxies is known as Arp 273. The interaction of galaxies is thought to be relatively common in the universe, particularly within galactic clusters, but the opportunity to directly observe one such as this is rare.
The two galaxies, with their nuclei separated by 100,000 light years, are located 300 million light years from Earth in the Andromeda constellation. A collision is actually thought to have already occurred, with UGC 1813 passing through the five times more massive UGC 1810. As a result, the smaller galaxy is now showing signs of intense star formation at its nucleus. It is possible, though, that they will collide again due to their gravitational attraction.
Most galactic collisions result in the merging of the two galaxies’ cores, but it’s unknown if that will happen in this case. What can be seen is a ‘bridge’ of sorts between the two where their spirals have been pulled apart by the other. It is thought that the interaction of Arp 273 may bear similarities to the eventual fate of our own galaxy when we collide with Andromeda in 4.5 billion years.

These two interacting galaxies are providing us with a rare opportunity to observe a galactic collision.
