Researchers have found that the Universe appears to be clumpier than predicted. This clumpiness, if not due to systematics, might be evidence that the standard model of cosmology needs to be rewritten.
Imagine yourself leaving Earth and looking at it as you are going further and further. You would first see …

Astrophysicists have always assumed that our Universe has a “mirror” symmetry. Researchers are now trying to test this assumption, and their first results show that our Universe might not be exactly as expected.
In a Universe with a mirror symmetry, the image of a counter-clockwise rotating galaxy is a galaxy with …

A few days ago, Expedition 27 came back from the ISS on board the Soyuz TMA-20 spacecraft. One of the crew members, flight engineer Paolo Nespoli (the others were Commander Dmitri Kondratyev and flight engineer Cady Coleman) had the occasion to take unique pictures of Endeavour docked to the ISS. …

A researcher has suggested that dark matter might simply be an illusion, rather than some unknown non-baryonic matter. Assuming that antimatter has a negative gravitational charge, the “illusion” would be explained by the resulting gravitational polarization of the quantum vacuum by ordinary matter.
The need for dark matter first appeared with …

A team of researchers explored the possibility of giant impacts on Earth-like planets resulting in a Moon-like satellite: according to their simulations, the phenomenon may be much more common than previously thought.
In the most popular scenario, our Moon formed after Earth and another planet collided: over time, the debris produced …
