Until recently the number of theories on the origin of fast radio bursts outnumbered the number of observations.
Many of the stars appearing in the night sky did not originate from within our galaxy.
The 7th International Conference on New Frontiers in Physics (ICNFP 2018) took place on 4–12 July in Kolymbari, Crete.
If extra dimensions are large, part of the gravitational field would “leak” into the extra dimensions and gravitational waves would be weaker than expected.
The 20th International Symposium on Very High Energy Cosmic Ray Interactions (ISVHECRI 2018) was held in Nagoya, Japan.
Some 180 years ago, a relatively normal star called Eta Carinae suddenly brightened to become the second brightest star in the sky, before almost disappearing at the end of the 19th century.
The discovery of large-scale features in the gamma-ray sky in approximately the same direction continues to puzzle researchers.
Gravity behaves the same way on a galactic scale as it does in our solar system, and alternative gravity models which remove the need for dark energy are disfavoured.
NASA’s Chandra X-ray Observatory have revealed a dozen stellar-mass black holes at the centre of the galaxy, providing the first observational evidence for such a black-hole cluster.
