Astronomers have used space-based telescopes, including NASA's Swift X-ray observatory, to watch a monster black hole spring to life with powerful X-ray eruptions.

The European Space Agency's XMM-Newton is playing a crucial role in investigating the longest and most energetic bursts of X-rays seen from a newly awakened black hole. Watching this strange behaviour unfold in real time offers a unique opportunity to learn more about these powerful events and the mysterious behaviour of massive black holes.

The human perception of stars is that they are largely unchanging although of course in reality stars and their host galaxies do change over time, just very VERY slowly. When galaxies deplete their star forming materials, they traditionally become redder as short lived stars die while long lived dwarf stars persist for trillions of years. However, recent research challenges this understanding.

Random flashes of radiation in the sky are not all that unusual. A few years ago, once such flash was detected coming from a star that at the time, was believed to be from a star consuming a planet! The exact mechanism was unsure though for example; was it the star bloating up as a red giant and engulfing the planet or did the planet spiral in toward the star? The answer was until now, a little elusive. Observations from the James Webb Space Telescope showed the environment around the star didn’t match a red giant so it must have been the planet crashing into the star!

The two most prominent satellite galaxies of the Milky Way are the Large and Small Magellanic Clouds. A team of astronomers have recently tracked the movements of 7,000 stars in the Small Magellanic Cloud (SMC) and found that many of them are being pulled away towards the Large Magellanic Cloud! It seems the SMC is being pulled apart, perhaps leading to its eventual destruction as the tidal forces strip away its stars!

For the first time since Russian cosmonaut Valentina Tereshkova’s solo flight in 1963, a spacecraft will fly with only women aboard. Blue Origin’s all-female crew includes pop star Katy Perry.

SpaceX scrubbed the launch of a Falcon 9 rocket early Friday for undisclosed reasons. It had been scheduled to loft 21 satellites for the company’s Starlink network.

One of the things about astronomy that captivates me is that for every question we answer, we open up a whole bunch of other questions. Dark matter and dark energy are one such phenomenon that rather continues to confound us. There’s also the mystery of missing infrared light too but a team of astronomers think they may have found it! The team examined a region of sky using the Herschel Space Telescope and, by staking 141 images, found where individual dust-rich galaxies appeared blended together. The galaxies are absorbing starlight and re-emitting infrared radiation, and is this that may well account for the missing light.
