When extreme and dangerous air pollution events strike and blanket the air with hazardous levels of pollution, it causes a major threat to public health and safety. It's also exceedingly challenging to monitor. The pollutants move quickly through the atmosphere, and can undergo chemical transformations from one form to another, leaving it difficult to predict the level of human exposure. I

The construction of a survey telescope array, which will be mainly used to detect space debris in medium and high orbits, has begun in northwest China's Qinghai Province, taking advantage of the plateau region's clear night skies. The multi-application survey telescope array, MASTA, developed by the Purple Mountain Observatory of the Chinese Academy of Sciences, is under construction in th

There is a significant discrepancy between theoretical and observed amounts of lithium in our universe. This is known as the cosmological lithium problem, and it has plagued cosmologists for decades. Now, researchers have reduced this discrepancy by around 10%, thanks to a new experiment on the nuclear processes responsible for the creation of lithium. This research could point the way to a more

A scientifically mysterious, isolated cloud bigger than the Milky Way has been found by a research team at The University of Alabama in Huntsville (UAH) in a "no-man's land" for galaxies. The so-called orphan or lonely cloud is full of hot gas with temperatures of 10,000-10,000,000 degrees Kelvin (K) and a total mass 10 billion times the mass of the sun. That makes it larger than the mass

There are certain rules that even the most extreme objects in the universe must obey. A central law for black holes predicts that the area of their event horizons - the boundary beyond which nothing can ever escape - should never shrink. This law is Hawking's area theorem, named after physicist Stephen Hawking, who derived the theorem in 1971. Fifty years later, physicists at MIT and elsew

Barrier-breaking woman aviator Wally Funk, 82, will join Jeff Bezos this month on the first crewed spaceflight for the billionaire's company Blue Origin, the firm announced Thursday. The trip is 60 years overdue for Funk, who was one of the Mercury 13 - the first women trained to fly to space from 1960-1961, but excluded because of their gender. On July 20, she will become the oldest pe

Rogue Space Systems Corporation announced the signing of a Letter of Intent by Orbital Assembly Corporation (OAC), the world's first large scale space construction company, to lease two Laura Orbital Robot (Orbots) spacecrafts for Orbital Assembly's P-STAR Mission to launch construction technologies for the first low gravity space hotel. As part of the agreement, Rogue Space and Orbital As

NASA is preparing to establish a regular cadence of trips to the Moon under Artemis. To help the agency fine-tune its approach, NASA will award firm fixed-price, milestone-based contracts of up to $45 million for commercial-led work under a broad agency announcement released Thursday. NASA is seeking new work to mature designs and conduct technology and engineering risk-reduction tasks for

This is the main camera that ESA's Hera mission for planetary defence will be relying on to explore and manoeuvre around the Didymos asteroid system. Hera - named after the Greek goddess of marriage - will be, along with NASA's Double Asteroid Redirect Test (DART) spacecraft, humankind's first probe to rendezvous with a binary asteroid system, a little understood class making up around 15%
