Supernova Death of Red Giant Directly Observed for 130 Days

Astronomers have imaged in real-time the dramatic end to a red supergiant’s life, watching the massive star’s rapid self-destruction and final death throes before it collapsed into a Type II supernova. “I am most excited by all of the new ‘unknowns’ that have been unlocked by this discovery,” says Jacobson-Galán. “Detecting more events like SN …

Earth to Jupiter Via Magsail in 21 Days and Neptune in 18 Weeks

Alex Tolley has written up an analysis of an improved plasma magnet sail concept called Wind Rider. Centauri Dreams covered the work. Nextbigfuture notes that the design looks very simple and achievable. If it works then by 2030s we would be able to mass produce probes by the thousands to explore the solar system and …

2022 Should See Start of Technology Demos Leading to High Resolution Exoplanet Imaging

A NASA NIAC Phase III is developing and plans to fly a 2022 TDM (Technology Demonstration Mission) to prove the SGLF’s (Solar Gravitational Lens Focus) mission architecture. They will then prepare a near-term (by 2024), low-cost (less than $40M) mission to fly through the solar system faster than any spacecraft ever ~7 AU/year, capable of …

Alien Microbe Life on Numerous Super Earth Exoplanets Should Be Observed By 2025

Ocean covered exoplanets that are up to 2.6 times bigger than Earth should have microbial life which the James Webb Space Telescope should detect. The James Webb should launch this year. Planets of this size dominate the known exoplanet population, although they have not been studied in nearly as much detail as super-Earths. Hycean worlds …

Evidence of Water Vapor at Jupiter’s Moon Ganymede

Astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter’s moon Ganymede. This water vapor forms when ice from the moon’s surface sublimates — that is, turns from solid to gas. Scientists used new and archival datasets from NASA’s Hubble Space Telescope to make the discovery. Previous research has offered circumstantial evidence that …

Black Hole and Neutron Star Collisions Detected Twice in Ten Days

Two instances of black hole-neutron star collision events have been detected using the Advanced LIGO and Virgo gravitational wave detectors, details of which have been published today in Astrophysical Journal Letters. Previous gravitational wave detections have spotted black holes colliding, and neutron stars merging, this is the first time that scientists have detected a collision …
