NASA’s NICER delivers best-ever pulsar measurements, first surface map

NASA’s NICER delivers best-ever pulsar measurements, first surface map Astrophysicists are redrawing the textbook image of pulsars, the dense, whirling remains of exploded stars, thanks to NASA’s Neutron star Interior Composition Explorer (NICER), an X-ray telescope aboard the International Space Station. Using NICER data, scientists have obtained the first precise and dependable measurements of both […]

Short-lived light sources discovered in the sky

Short-lived light sources discovered in the sky A project lead by an international team of researchers use publicly available data with images of the sky dating as far back as the 1950s to try to detect and analyse objects that have disappeared over time. In the project “Vanishing & Appearing Sources during a Century of […]

Research group confirm planet-mass objects in extragalactic systems

Research group confirm planet-mass objects in extragalactic systems A University of Oklahoma research group is reporting the detection of extragalactic planet-mass objects in a second and third galaxy beyond the Milky Way after the first detection in 2018. With the existing observational resources, it is impossible to directly detect planet-mass objects beyond the Milky Way […]

Wow, Meade Instruments Just Filed for Bankruptcy Protection

Wow, Meade Instruments Just Filed for Bankruptcy Protection Meade Instruments, a company familiar to any backyard astronomer who’s drooled over their telescopes, has filed for bankruptcy. The company has fallen on hard times in recent years, as they’ve faced increasing competition. Meade also recently lost a lawsuit, which pushed them over the edge into bankruptcy. […]

ALMA spots most distant dusty galaxy hidden in plain sight

ALMA spots most distant dusty galaxy hidden in plain sight Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted the light of a massive galaxy seen only 970 million years after the Big Bang. This galaxy, called MAMBO-9, is the most distant dusty star-forming galaxy that has ever been observed without the help of […]

A new way to measure cosmic black holes

A new way to measure cosmic black holes Supermassive black holes are the largest black holes, with masses that can exceed a billion Suns. Just this spring, the first-ever image of the supermassive black hole at the center of the Messier 87 galaxy was taken, and researchers recently spotted the largest supermassive black hole ever […]

Relativistic jet of the blazar S5 0836+710 investigated in detail

Relativistic jet of the blazar S5 0836+710 investigated in detail Using very long baseline interferometry (VLBI), astronomers have performed comprehensive multiwavelength observations of the radio emission in the blazar S5 0836+710. The new research, presented in a paper published December 2 on arXiv.org, reveals important insights about the structure the blazar’s relativistic jet. phys.org Go […]

X-ray satellite XMM-Newton celebrates 20 years in space

X-ray satellite XMM-Newton celebrates 20 years in space Two decades ago, on Dec. 10, 1999, an Ariane 5 rocket climbed into the morning sky from Kourou, French Guiana. It carried into orbit the X-ray Multi-Mirror Mission (XMM-Newton), the largest scientific spacecraft yet built by ESA (European Space Agency) and a pioneering satellite for studying the […]

Second stellar population found in Milky Way’s thick disk

Second stellar population found in Milky Way’s thick disk A new study on the kinematics and chemical composition of a sample of stars in the vicinity of the sun, led by Dr. Daniela Carollo, researcher of the Italian National Institute for Astrophysics, has revealed that the stars that make up the thick disk of the […]

Water common—yet scarce—in exoplanets

Water common—yet scarce—in exoplanets The most extensive survey of atmospheric chemical compositions of exoplanets to date has revealed trends that challenge current theories of planet formation and has implications for the search for water in the solar system and beyond. phys.org Go to Source

This is the Milky Way’s Magnetic Field

This is the Milky Way’s Magnetic Field The Milky Way galaxy has its own magnetic field. It’s extremely weak compared to Earth’s; thousands of times weaker, in fact. But astronomers want to know more about it because of what it can tell us about star formation, cosmic rays, and a host of other astrophysical processes. […]

NASA’s TESS Watched an Outburst from Comet 46P/Wirtanen

NASA’s TESS Watched an Outburst from Comet 46P/Wirtanen TESS, the Transiting Exoplanet Survey Satellite, has imaged an outburst from the comet 46P/Wirtanen. It caught the outburst in what NASA is calling the clearest images yet of a comet outburst from start to finish. A comet outburst is a significant but temporary increase in the comet’s […]

Stardust from red giants

Stardust from red giants Some of the Earth’s building material was stardust from red giants, researchers from ETH Zurich have established. They have also explained why the Earth contains more of this stardust than the asteroids or the planet Mars, which are farther from the sun. phys.org Go to Source
