The Space Variable Objects Monitor is a small X-ray telescope satellite for studying the explosions of massive stars by analysing the resulting gamma-ray bursts, developed by China National Space Administration (CNSA), Chinese Academy of Sciences (CAS) and the French Space Agency , [45] launched on 22 June 2024 (07:00:00 UTC).
Artist's impression of neutron stars merging, producing gravitational waves and resulting in a kilonova Kilonova illustration. A kilonova (also called a macronova) is a transient astronomical event that occurs in a compact binary system when two neutron stars or a neutron star and a black hole merge. [1]
Now new research claims to have shown that the explosion is in fact a nearly perfect sphere, and is completely symmetrical. Scientists have pursued a number of possible explanations – such as ...
Multiple telescopes observed a rare cosmic explosion called a kilonova that created heavy elements in space, including some necessary for life. Explosion 1 million times brighter than the Milky ...
Consequently, it is likely that Betelgeuse has not always had its current motion through space but has changed course at one time or another, possibly the result of a nearby stellar explosion. [ 97 ] [ 149 ] An observation by the Herschel Space Observatory in January 2013 revealed that the star's winds are crashing against the surrounding ...

Stellar explosion can refer to: Nova; Kilonova; Micronova; Supernova. Type Ia supernova; Type Ib and Ic supernovae; Type II supernova; Superluminous supernova; Pair-instability supernova; Hypernova; Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova
It was initially estimated to have a much lower mass, and thus a low density of 3.3 ± 0.9 g/cm 3 and a surface gravity around 6.1 m/s 2 (62% of Earth's value). [1] This suggested a large amount of volatiles , with a 2017 study suggesting that a water ocean may comprise as much as 20% of the planet's mass, increasing the temperature at the ...
