- An out-of-control Soviet spacecraft, Kosmos 482, which launched in 1972 and was intended for Venus, crash-landed back on Earth.
- The descent capsule of Kosmos 482, designed to withstand intense heat, may have broken up over the Indian Ocean according to Roscosmos and Nasa.
- The exact landing site of the spacecraft is uncertain, with predictions pointing to the Indian Ocean west of Jakarta, Indonesia, but a potential wide window of landing sites include southern England.
- European Space Agency confirms the satellite decayed within the estimated re-entry window, with no visual observation of the final re-entry pointing towards a possible ocean landing.

Roaming black hole devours star in deep space: A rare cosmic event
- Astronomers using NASA’s Hubble Space Telescope observed a massive black hole consuming a star 600 million light-years away in a rare cosmic event known as a tidal disruption event (TDE).
- The TDE, named AT2024tvd, is unique as it occurred far from the center of its host galaxy, indicating the presence of a 'wandering' black hole roaming through the galaxy's outskirts.
- The galaxy hosting AT2024tvd contains two massive black holes, with the wandering one weighing about 1 million solar masses and was confirmed to be in an offset position.
- The discovery of AT2024tvd sheds light on the existence of roaming black holes and may help in identifying more of them through similar tidal disruption events, as suggested by lead study author Yuhan Yao of UC Berkeley.

New quantum theory of gravity could unlock the mysteries of the universe
- Researchers at Aalto University in Finland have developed a new theory that aims to unify all fundamental forces of nature into a 'theory of everything.'
- The new theory treats gravity as a gauge theory, similar to how the other three forces are described, which could potentially bridge the gap between general relativity and quantum field theory.
- This novel approach to gravity is designed to match the symmetries of the standard model of particle physics, offering a promising way to integrate gravity with quantum mechanics.
- While early tests show promise, further work, including the process of renormalization, is required to fully prove the theory's compatibility with existing frameworks.

Soviet spacecraft Kosmos 482 crashes back to Earth, disappearing into Indian Ocean after 53 years in orbit
- Soviet spacecraft Kosmos 482, designed to land on Venus, crash-landed into the Indian Ocean after 53 years in orbit.
- Launched in 1972, Kosmos 482 was part of the Soviet Union's Venera program but malfunction led to its marooned elliptical orbit around Earth.
- The Kosmos-482 spacecraft disintegrated and fell into the Indian Ocean; no damage or injuries reported.
- Scientists highlight the growing risk of hazardous debris orbiting Earth's skies, emphasizing the low likelihood of anyone being harmed by falling space debris.

Celebrating Black Hole Week with a Spotlight on a Research Paper
- Astronomers from Yale University discovered an unusual straight line next to a galaxy over 10 billion light years away during observations from the Hubble Space Telescope.
- The thin line pointed directly at the center of a nearby dwarf galaxy, almost half as bright as its neighbor, and was found to be some 200 thousand light years long.
- Further examination revealed that the dwarf galaxy had merged with another galaxy about 100 million years ago, resulting in higher star formation rates and other unique qualities.
- When galaxies merge, the black holes at their centers also interact, potentially leading to the expulsion of a black hole, which could explain the observed bizarre line in the observations.
- The observed feature was interpreted as a black hole being ejected from the galaxy, travelling through space at an incredibly high speed and causing stars to form in its wake.
- This phenomenon, termed a runaway black hole, is a rare and fascinating event, with the ejected black hole being 40 times larger than the Sun and moving at 16,000 kilometers per second.
- The discovery was described as a serendipitous find by lead researcher Pieter van Dokkum and showcases the exciting and unexpected phenomena that can be observed in the universe.
- Advancements in technology and telescopes offer promise for uncovering more wondrous astronomical events in the future, pushing the boundaries of our understanding of the cosmos.
- This discovery adds to the collection of extraordinary astronomical phenomena, with the potential for more such discoveries on the horizon as our observational tools improve.
