It is clear to everyone that astronomy at all events compels the soul to look upwards, and draws it from the things of this world to the other.

From boring to bursting: a giant black hole awakens

ESO Top News - 15 hours 41 min ago

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 Small Magellanic Cloud is Being Torn Apart

Universe Today - Thu, 04/10/2025 - 8:06pm

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!

Astronomers Think They've Found the Universe's Missing Infrared Light

Universe Today - Thu, 04/10/2025 - 7:38pm

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.
