Obviously there are no cows on Mars but NASA’s Mars Curiosity Rover detected an increase of methane in the atmosphere and organic molecules from the soil during one of...

New insight into the minor merger process

Galaxy mergers are violent interactions between galaxies and they are consider one of the fundamental steps in how galaxies form and evolve. Mergers occur when two (or more) galaxies...

Some Earths Like It Hot

Planetary systems form from the same cloud as its parent star. As the cloud contracts under the effect of gravity, the gas acquires more angular velocity. Spinning faster it...

The Very Hungry Supermassive Black Hole

0
We all get the munchies, but when you're a supermassive black hole (SMBH) your hunger might have dire consequences. And just like that an SMBH has outgrown its galaxy and jumped to the top of the heavyweight objects in the universe. About 12 billion light years from us, there is a galaxy called CID-947. It has a mass similar to our own Milky Way (about 1000 billion times the mass of the Sun) and it was only remarkable because it had an active galactic nucleus (AGN, i.e. an accreting SMBH).

Interstellar Travel Meets The Real Universe

Interstellar travel is about to go from a Sci-fi idea to physical reality, but the jump comes with a series of considerations that fiction writers don't have to consider. This...

Probing the furthest Universe to understand how spiral galaxies formed.

0
A new paper accepted for publication this month has highlighted how spiral galaxies came to form in the early Universe. By using the power of the Atacama Large Millimeter/submillimeter Array...

Negative mass could theoretically exists in our Universe

Saoussen Mbarek and Manu Paranjape at the Université de Montréal in Canada have published a paper that details the conditions for negative mass to exist in our Universe without...

The Big Bang is not going anywhere.

0
On the 4th of February a paper was published detailing a Universe that didn’t need a Big Bang. While it is very interesting (you can read it here) I find myself once again at odds with how theoretical papers are formulated. The paper details a mathematical robust way to solve many cosmological conundrums. The flatness problem (discussed in this vlog), the value of dark energy and the nature of dark matter.
