SMC in Gravitational Trouble: New Study Shows It’s Being Torn Apart by Its Big Neighbor

A decade of VISTA survey data reveals the Small Magellanic Cloud is being stretched and dragged apart by the gravitational pull of the Large Magellanic Cloud, with most SMC stars moving outward at about 38,000 mph (61,000 km/h). The findings argue the SMC isn’t a stable rotating disk but is undergoing tidal disruption due to repeated LMC encounters, potentially tearing the dwarf galaxy in two long before the Milky Way–SMC–LMC collision in ~2.4 billion years. The study, published in Astronomy & Astrophysics, highlights the dynamic nature of Milky Way satellites and will be further explored with the One Thousand and One Magellanic Fields survey.

Phobos Could Become Mars's Rings Sooner Than Thought

Two independent analyses indicate Phobos, a weak, rubble‑pile moon, could shed surface material and be torn apart into rings long before crossing Mars’s Roche limit, via staged mass‑loss events around 2.25–2.09 Mars radii and possibly a sesquinary catastrophe; the MMX mission (launch 2026) will study its interior to better determine its fate.

Astronomers Witness a Star Being Torn Apart by a Black Hole in Real Time

Astronomers are watching what appears to be a star being shredded by a black hole, offering a rare real-time view of a tidal disruption event and the extreme physics of how black holes feed on stars, with signals expected across the electromagnetic spectrum.

Stars Near Black Holes Live Longer and Lead Strange Lives

New research shows that stars passing close to the Milky Way's supermassive black hole can survive, become brighter, and undergo chemical changes, providing insights into black hole feeding habits and possibly explaining mysterious G objects at the galaxy's core.

Earth-sized exoplanet spirals toward destruction

A newly discovered ultra-short-period exoplanet, TOI-2431 b, is an Earth-sized lava world orbiting its star every 5.4 hours, with a high likelihood of being torn apart or spiraling into its star within about 31 million years, serving as a dramatic example of extreme planetary physics and the harsh realities of worlds beyond our solar system.

Closest-ever observation of "Scary Barbie" black hole spaghettifying a star.

Astronomers have discovered a supermassive black hole, nicknamed "Scary Barbie," that has ripped apart a massive star in a process called "spaghettification." The event is one of the most energetic and luminous transients ever observed, exceeding any observed or theorized supernova. The black hole's luminosity is still evolving and could be visible for several more years. Researchers hope continued observation using NASA's James Webb and Hubble Space Telescopes will eventually allow them to identify Barbie's host galaxy. The discovery was made with the help of an artificial intelligence engine called the Recommender Engine For Intelligent Transient Tracking (REFITT).

Black hole's destructive power revealed: Giant star and dust cloud torn apart

Astronomers have discovered an extremely bright and long-lived transient object, named "Scary Barbie," which is believed to be a supermassive black hole consuming a massive star through tidal disruption. The object is the most energetic phenomenon ever encountered and has lasted for over 800 days, much longer than usual transients. The discovery was made using big data analysis and AI engine, REFITT, which combs through millions of alerts from telescopes around the world. The discovery highlights that there are still mysteries to uncover in the universe.
