Kentucky-based astrophotographer David Joyce has shared a glorious deep space vista revealing the fossil light of a vast supernova remnant created in the death throes of an enormous star some 10,000 years ago. Joyce’s nebula scene captures the expanding shell of the supernova remnant CTB 1, also known as both the Garlic Nebula and the Medulla Nebula for its resemblance …

An anonymous reader shares a report: In a preprint titled “Can LIGO Detect Daylight Savings Time?,” Reed Essick, former LIGO member and now a physicist at the University of Toronto, gives a simple answer to the paper’s title: “Yes, it can.” The paper, which has yet to be peer-reviewed, was recently uploaded to arXiv. That might seem like an odd …

Tracking gravitational waves—invisible ripples in space-time from intense astronomical events—pushes the limits of what astronomers must do to reduce unwanted noise. Scientists have been getting increasingly better at doing just that, but new research warns that something rather unexpected might be getting in the way: daylight savings time. In a preprint titled “Can LIGO Detect Daylight Savings Time?,” Reed Essick, …

A glowing hand stretches across the cosmos, with its palm and fingers sculpted from the wreckage of a massive stellar explosion. The eerie structure is part of the nebula MSH 15-52, powered by pulsar B1509-58 — a rapidly spinning neutron star that is only about 12 miles (20 kilometers) in diameter. By combining radio data from the Australia Telescope Compact …

For the first time, researchers have recreated the universe’s first ever molecules by mimicking the conditions of the early universe. The findings shake up our understanding of the origin of stars in the early universe and “calls for a reassessment of the helium chemistry in the early universe,” …

Outdoor lighting for buildings, roads and advertising can help people see in the dark of night, but many astronomers are growing increasingly concerned that these lights could be blinding us to the rest of the universe. An estimate from 2023 …

The test tube carrying the Pakistan-origin wheat seeds was aboard the SpaceX Dragon Capsule, which was launched from Nasa’s Kennedy Space Centre on August 1. Space, as all Trekkies agree, is the final frontier. It is mysterious, magnificent, mighty, and draws in earthlings who have long dreamed of exploring other worlds. In recent years, these dreams have crossed over from …
