A Soviet-era spacecraft built to land on Venus is falling to Earth instead
- Soviet-era spacecraft Kosmos 482, meant to land on Venus, is set to reenter Earth's atmosphere after a misfire over 50 years ago.
- Kosmos 482, about a half-ton in mass, was designed with a titanium heat shield to survive Venus' extreme conditions and now faces reentry into Earth.
- The spacecraft has a good chance of surviving the plunge through Earth's atmosphere, as its design is meant to withstand high pressures and temperatures.
- Although most space debris burns up during reentry, the European Space Agency predicts that Kosmos 482 is likely to reach Earth's surface intact.

NASA’s Hubble Pinpoints Roaming Massive Black Hole
- NASA's Hubble Space Telescope has discovered a massive black hole roaming 600 million light-years away, consuming stars in a tidal disruption event (TDE).
- The new TDE, named AT2024tvd, revealed a wandering supermassive black hole that is offset from the center of the galaxy, a rare find among TDE events.
- This offset black hole weighs one million solar masses and coexists with a 100 million solar mass central black hole within the same galaxy.
- The TDE phenomenon involves a star being ripped apart by a black hole's gravitational forces, leading to the formation of a disk around the black hole and the emission of high-temperature radiation.
- The flare from the TDE was detected by ground-based telescopes and confirmed by NASA's Chandra X-ray Observatory, with Hubble pinpointing the event's location within the galaxy.
- The black hole responsible for the TDE is suspected to have been ejected from the galaxy's center due to three-body interactions or may be a remnant from a past galaxy merger.
- Future telescopes like the Vera C. Rubin Observatory and NASA's Nancy Grace Roman Space Telescope will aid in further understanding transient events like TDEs.
- This discovery opens up possibilities for uncovering more wandering black holes and sheds light on the dynamics of supermassive black holes in galaxies.
- The collaborative efforts of telescopes like Hubble and Chandra enable scientists to study and track rare celestial events, enhancing our knowledge of the universe.
- Hubble's continued operation and groundbreaking discoveries underscore its vital role in advancing astrophysical research and understanding the cosmos.

Did astronomers just discover the smallest galaxy in the universe?
- UMa3/U1, a recently discovered astronomical object, poses a challenge in defining whether it is a small galaxy or a star cluster.
- The distinction between Ultra-Faint Dwarfs (UFDs) and star clusters is blurred due to the significant presence of dark matter in UFDs.
- UMa3/U1 is exceptionally small, measuring only 20 light-years across with around 60 stars and a visible mass equivalent to 16 Suns.
- Based on current evidence, UMa3/U1 is likely a stable star cluster, although more observations are needed to confirm its classification.

NASA peers into a blazar’s heart and solves a 30-year-old mystery
- NASA's Imaging X-ray Polarimetry Explorer (IXPE) has helped scientists uncover the mystery behind how X-rays are generated in powerful jets from supermassive black holes, specifically focusing on a blazar called BL Lacertae (BL Lac).
- The study revealed that X-rays in these jets are produced by electrons through Compton Scattering, not protons, as scientists previously debated, and the X-rays showed low polarization compared to optical polarization.
- IXPE, launched in December 2021, collaborated with radio and optical telescopes to observe BL Lac, leading to groundbreaking findings that shed light on the mechanisms of X-ray generation in extreme environments.
- The discovery not only solved a longstanding mystery about supermassive black hole jets but also highlighted the importance of IXPE in challenging scientific assumptions and exploring new possibilities in the study of blazars.
