NASA’s Chandra X-ray spacecraft finds ‘danger zones’ around stars (Image Credit: Space.com) Using NASA’s space-based Chandra X-ray Observatory and the retired Spitzer Space Telescope, astronomers have discovered “danger zones” for planets that are forming around young stars. The team found these treacherous regions by performing long-term observations of an object known as […]
Scientists just found a mind-boggling object in deep space (Image Credit: Mashable) NASA says it best: “Neutron Stars Are Weird!“ They are extraordinarily compact. Just a sugar cube-sized piece of this extremely dense material — the remnants of a collapsed, exploded star — weighs 1 billion tons. They’re known to rotate quickly, […]
Scientists have figured out why Martian soil is so crusty (Image Credit: Phys.org) Artist’s concept of InSight “taking the pulse of Mars”. Credit: NASA/JPL-Caltech On November 26, 2018, NASA’s Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) mission landed on Mars. This was a major milestone in Mars exploration since it was the […]
Another way to extract energy from black holes? (Image Credit: Phys.org) Illustration of a powerful black hole and its magnetic field. Credit: L. Calçada/ESO The gravitational field of a rotating black hole is powerful and strange. It is so powerful that it warps space and time back upon itself, and it is so strange that […]
Viewpoint: Carl Sagan’s scientific legacy extends far beyond ‘Cosmos’ (Image Credit: Phys.org) Credit: Pixabay/CC0 Public Domain On Nov. 9, 2024, the world will mark Carl Sagan’s 90th birthday—but sadly without Sagan, who died in 1996 at the age of 62. Most people remember him as the co-creator and host of the 1980 “Cosmos” television series, […]
Next-generation space materials blast off for tests on ISS (Image Credit: Phys.org) Credit: NASA A new generation of space materials left Earth on November 5 as they head to the International Space Station (ISS) to undergo testing in the brutal conditions of low Earth orbit. Developed at the University of Bristol, these high-performance materials could […]
World’s first wooden satellite launched into space (Image Credit: Phys.org) LignoSat, a satellite made from wood and developed by scientists at Kyoto University and Sumitomo Forestry, shown during a press conference in May, 2024. The world’s first wooden satellite has blasted off on a SpaceX rocket, its Japanese developers said Tuesday, part of a resupply […]

How many additional exoplanets are in known systems? (Image Credit: Phys.org) The seven planetary systems considered. Credit: arXiv (2024). DOI: 10.48550/arxiv.2411.00245 One thing we’ve learned in recent decades is that exoplanets are surprisingly common. So far, we’ve confirmed nearly 6,000 planets, and we have evidence for thousands more. Most of these planets were discovered using […]
