How much can you learn from a microscopic drop of ancient seawater? More than you might think, a new study shows. Researchers have analysed a series of such drops and arrived at an estimate that the process that underpins Earth’s plate tectonics may have started some 600 million years earlier than previously thought. Plate tectonics – the

After 16 days in space, the crew of the Space Shuttle Columbia was due to return to Earth. Residents of Texas watched as the shuttle glowed brightly in the clear blue Texas sky. Slowly, a realization that something was wrong dawned on them. Rather than one, bright, burning spot, as to be expected, there were
Black holes can get pretty big, but there’s a special class that is the biggest of the big, absolute yawning monster black holes. And astronomers seem to have found an absolute specimen, clocking in at 40 billion times the mass of the Sun. It’s at the centre of a galaxy called Holmberg 15A, a supergiant
We all know that Antarctica’s ice is melting into the ocean faster than ever, but we haven’t had a lot of information on how exactly that ice makes its way across the continent. A team of scientists has now pored over decades of satellite data to change this, and have developed the most precise map of
LOGAN, Utah — Spaceflight announced Aug. 6 that it will purchase the first commercial launch a new Indian vehicle scheduled to make its debut later this year. Spaceflight said it will launch payloads for an undisclosed U.S. satellite constellation customer on a flight of the Small Satellite Launch Vehicle (SSLV), a derivative of the existing,
Einstein deriving special relativity, for an audience of onlookers, in 1934. The consequences of applying relativity to the right systems require that, if we demand energy conservation, E = mc^2 must be valid.

On Wednesday, July 24th, the people of the Great Lakes region were treated to a spectacular sight when a meteor streaked across the sky. The resulting fireball was observed by many onlookers, as well as the University of Western Ontario’s All-Sky Camera Network. This array runs across southern Ontario and Quebec and is maintained in
LOGAN, Utah – NanoAvionics isn’t ready to disclose names but the company has lined up customers for the first nanosatellites it plans to build in Midland, Texas, NanoAvionics CEO Vytenis Buzas, told SpaceNews. NanoAvionics, a spinoff of Lithuania’s Vilnius University with about 80 employees conducting research and development in northern and western Europe, is preparing

Astronauts on board the International Space Station (ISS) have to do just about everything for themselves. Living within this constantly orbiting laboratory, they’re not only crew members, they’re also plumbers, janitors and housekeepers. Just last week, in fact, the team of six astronauts currently on board began a month-long chore that requires taking their trash
The Air Force integrated a 12U cubesat on the Centaur’s aft bulkhead carrier. WASHINGTON — A United Launch Alliance Atlas 5 rocket scheduled to launch a $1.1 billion military communications satellite on Thursday will carry an experimental cubesat as a rideshare payload on the back of the Centaur, the Atlas’ upper stage. The main payload
Tau Zero imagines exoplanets within our grasp. Tau Zero / Adrian Mann My regular readers appreciate the fact that NASA is partnering with a number of commercial space businesses to permanently expand the human frontier into cis-Lunar space. While $20 billion in federal funding drives NASA’s amazing programs, the agency doesn’t get that money without strong
When Grandma Fish was just a tiny fry, the Titanic was yet to set sail. Humans had yet to reach the South Pole. The First World War wasn’t even a rumble on the horizon, the first public radio broadcast yet to spill its arias into New York City. As new dating techniques have revealed, one
If you spend any time on social media, it can seem that the general public doesn’t have much confidence in science. People are still arguing that Earth is flat, vaccinations cause autism, or climate change isn’t caused by humans, while science communicators keep providing evidence on topics that have been considered settled for decades or even centuries.
Another ancient star has been found lurking in the Milky Way. Around 35,000 light-years away, a red giant star named SMSS J160540.18–144323.1 was found to have the lowest iron levels of any star yet analysed in the galaxy. This means that it’s one of the oldest stars in the Universe, probably belonging to the second
LOGAN, UTAH – LeoLabs, a space situational awareness company, unveiled a small satellite tracking service called LeoTrack Aug. 5 at the Small Satellite Conference here. LeoTrack, which LeoLabs sells through web-based subscriptions, provides small satellite and cubesat operators with a range of services and information including spacecraft tracking, orbital state vectors, predictive radar availability, scheduled

For many 17-year-olds, the movie title Clueless can be an apt description. At that
Baby jumping spiders have vision that’s almost as extraordinarily good as the grown-ups, scientists have discovered – despite the baby spiders being around a hundredth of the size. A new study reports on how this feat of biological engineering is achieved. The teeny tiny spiderlings pack the same number of light-capturing photoreceptors into their four pairs
July was likely the hottest month in recorded history, according to new data from the World Meteorological Organisation (WMO) released last Thursday. According to the report, findings from the Copernicus Climate Change Program indicate that temperatures recorded in the first 29 days of July were as hot or marginally hotter than the previous record month,
