Magnetars are among the rarest—and weirdest—denizens of the galactic zoo. They have powerful magnetic fields and may be the source of fast radio bursts (FRBs). A team of astronomers led by European Space Agency researcher Ashley Chrimes recently used the Hubble Space Telescope (HST) to track one of these monsters called SGR 0501+4516 (SGR0501, for […] How do robots feel in space? This is both a practical and possibly an existential question. Still, today, we’ll focus on the practical side by looking at a review paper from Hadi Jahanshahi and Zheng Zhu of York University in Canada that discusses different tactile sensor types and their advantages and disadvantages for use in […] Getting missions to land successfully on the moon has been difficult. Recent missions, such as IM-1 and IM-2, which the private company Intuitive Machines completed, have been qualified successes at best, with both landers settling at unintended angles and breaking parts of them off along the way. Such experiences offer excellent learning opportunities, though, and […] In 2020, astronomers detected WD 1856+534 b, a gas giant that orbits a star 81 light-years from Earth. This exoplanet, which is roughly six times the mass of Jupiter (making it a “super-Jupiter”), was the first transiting planet known to orbit a white dwarf (WD) star. In a recent paper, an international team of astronomers […] The solar system consists of our star, the sun, and everything bound to it by gravity: the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, along with dwarf planets like Pluto, dozens of moons, and millions of asteroids and comets. The planets orbit the sun in elliptical paths, with the inner four being […] Comets that have hit Earth have been a mixed bag. Early in Earth’s history, during the solar system’s chaotic beginning, they were likely the source of our planet’s water, ultimately making up about 0.02% of the planet’s mass. (Mars and Venus received a similar fraction.) Go to Source Three Chinese astronauts landed back on Earth on Wednesday after six months on China’s space station. Go to Source ESA’s Biomass satellite, designed to provide unprecedented insights into the world’s forests and their crucial role in Earth’s carbon cycle, has been launched. The satellite lifted off aboard a Vega-C rocket from Europe’s Spaceport in Kourou, French Guiana, on 29 April at 11:15 CEST (06:15 local time). Go to Source New data from the agency’s Jovian orbiter sheds light on the fierce winds and cyclones of the gas giant’s northern reaches and volcanic action on its fiery moon. Go to Source Stars in the Milky Way tend to form in families, with similar stars springing to life in roughly the same place at roughly the same time. These stars later head out into the wider galaxy when they’re ready to fly the nest. While smaller groups can completely dissipate, siblings from sizable families usually move similarly […] By analyzing the data from the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have investigated a star-forming region known as G34.26+0.15. As a result, they discovered an explosive outflow in this complex. The study was reported in a paper published on April 22 on the arXiv preprint server. Go to Source The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space Telescope (JWST) in an area of the sky called COSMOS Web. The study marks a major milestone in extragalactic astronomy, providing unprecedented insights into the formation and evolution of galaxies and […] Astronomers have discovered a previously unknown birthplace of some of the universe’s rarest elements: a giant flare unleashed by a supermagnetized star. The astronomers calculated that such flares could be responsible for forging up to 10% of our galaxy’s gold, platinum and other heavy elements. Go to Source Three Chinese astronauts’ return to Earth has been postponed owing to weather conditions. Go to Source Using the Spektr-RG (SRG) space observatory, astronomers from the Russian Academy of Sciences have inspected a radio-loud quasar known as SRGA J2306+1556, which is extremely luminous in the X-ray band. Results of the new study are reported in a research paper published April 18 on the arXiv preprint server. Go to Source […] |
