2+ hour ago   (699+ words) Planets are assembled inside broad disks of gas and dust around young stars, but those disks do not last forever. A new James Webb Space Telescope survey shows that winds from young, Sun-like stars can remove the gas while planets…...

1+ day, 20+ hour ago   (565+ words) Earth’s shadow will cover about 93 percent of the full Moon during the 27–28 August 2026 deep partial eclipse. It will be visible from the Americas, Europe, Africa, and western Asia. The full Moon will pass through Earth’s shadow on the night of…...

1+ day, 22+ hour ago   (717+ words) TIC 433545934 contains two pairs of stars locked in a wider orbit. The pairs eclipse internally, and observations also caught one binary crossing the other—a rare geometry that lets astronomers measure four stars together. Astronomers have identified a four-star system…...

3+ day ago   (656+ words) The Tarantula Nebula is one of the busiest stellar nurseries in our galactic neighbourhood. Thousands of young stars are packed into a web of gas and dust in the Large Magellanic Cloud, about 160,000 light-years away. Now three NASA space telescopes…...

3+ day, 5+ hour ago   (711+ words) They use a chain of methods rather than one universal measuring tape. Radar can reach planets. Parallax works for nearby stars. Farther out, astronomers compare known brightnesses, stellar pulsations and the stretching of light. Each step is checked against the…...

3+ day, 7+ hour ago   (405+ words) Boyajian’s Star may have a large companion orbiting it, according to a new study of the system’s motion. The best estimate puts the object at about 9.4 times the mass of Jupiter, but the uncertainty extends well into brown-dwarf territory. That…...

4+ day, 5+ hour ago   (630+ words) What are Lagrange points? They are five regions in a two-body system where the gravity of the larger bodies and the motion of a smaller object combine in a useful way. A spacecraft placed near one of these regions can…...

5+ day ago   (721+ words) Interstellar visitors are hard to find and even harder to classify. Survivorship bias may shape what we think we know about objects like ‘Oumuamua and 3I/ATLAS. Astronomers have confirmed three visitors from beyond the Solar System: 1I/‘Oumuamua, 2I/Borisov and 3I/ATLAS....

5+ day, 21+ hour ago   (679+ words) Jupiter’s Great Red Spot is a storm system wider than Earth, turning inside the planet’s cloud tops for centuries of recorded observation. It is not a solid mark on the surface. Jupiter has no solid surface beneath the visible clouds;…...

6+ day ago   (802+ words) A new study proposes using gamma-ray sources to search for the universe’s fossil neutrinos, a relic signal left from the first seconds after the Big Bang. The Universe should be filled with a faint bath of ancient neutrinos left over…...
