Blue Origin is stepping back up to the plate and will take another crack at launching its 98-meter-tall (321 ft) rocket from Cape Canaveral Space Force Station on Thursday, Nov. 13.
As the COP30 climate conference gets underway in Brazil, the world’s attention is once again drawn to the plight of the Amazon – the planet’s largest and most vital rainforest. With the European Space Agency’s Earth Explorer Biomass satellite now in orbit, ESA is helping Brazil prepare to transform this new mission’s groundbreaking data into actionable knowledge for protecting the rainforest and confronting climate change.
Tracking time is one of those things that seems easy, until you really start to get into the details of what time actually is. We define a second as 9,192,631,770 oscillations of a cesium atom. However, according to Einstein’s theory of general relativity, mass slows down these oscillations, making time appear to move more slowly for objects in large gravity wells. This distinction becomes critical as we start considering how to keep track of time between two separate gravity wells of varying strengths, such as on the Earth and the Moon. A new paper pre-print on arXiv by Pascale Defraigne at the Royal Observatory of Belgium and her co-authors discusses some potential frameworks for solving that problem and settles on using the new Lunar Coordinate Time (TCL) suggested by the International Astronomical Union (IAU).
The launch helped strengthen Europe's ambitions in climate monitoring, disaster response and maritime security.
The 100AZ is our best telescope for beginners and kids, with a host of user-friendly features that make viewing the moon and planets a breeze. Now, with $106 off, it's also a bargain telescope buy.
Parts of Earth's magnetic field work in reverse compared to what long-standing models predict, new research suggests.
Brie Larson and Benny Safdie join the original vocal cast for this cosmic Super Mario Brothers sequel.
Scientists may have solved the mystery of an "impossible" merger between two black holes so massive and fast-spinning that they shouldn't even exist, according to current theory.
The ESA's Euclid space telescope has been in space for just over a year, investigating some of the deepest mysteries of the cosmos. By observing cosmic structures up to a distance of 10 billion light-years, the observatory will chart the evolution of the Universe, attempt to constrain the influence of Dark Energy, and study the morphology of galaxies. In terms of galaxies, Euclid will attempt to answer the question of why the Universe contains such a variety of galaxies, characterized by size, shape, and colours.
Rocket Lab has delayed the first launch of its medium-lift Neutron rocket to 2026, founder and CEO Peter Beck said during a company earnings call on Nov. 10.
Last night's aurora painted the sky in reds, greens and even oranges. It's expected to return tonight!
Blue Origin needed a ship to catch rockets falling from space. They bought a massive roll-on/roll-off cargo ferry, hired engineers to convert it, and named it Jacklyn after Jeff Bezos's mother. Then, after four years of work, they scrapped the entire project and started over.
According to the textbook version of Solar System formation, planets should orbit the Sun in elliptical orbits, all lined up in the same plane. Jupiter, Saturn, Uranus, and Neptune don't follow this script. Their orbits are a little more elliptical and tilted relative to each other, not dramatically, but enough to puzzle astronomers for decades. Standard formation models predict the giant planets emerged from the protoplanetary disk on the same plane as the rest of the planets. Instead, something seems to have pushed them off course.
Early one February morning in 2025, Adam Borucki discovered something extraordinary behind his warehouse in Poland, a charred metal tank, roughly 1.5 metres across, sitting in his back yard. It had crashed from space during the night, part of a SpaceX Falcon 9 rocket that failed to complete its controlled descent into the Pacific Ocean. The debris damaged some electrical equipment and a concrete block. Nobody was hurt, but the incident raised an uncomfortable question; who pays when a private company's space hardware crashes into your property?
The supernova was the death of a red supergiant star 500 times larger than the sun, in a galaxy just 22 million light-years away.
New observations from the Virtual Telescope Project reveal 3I/ATLAS's sharply defined ion tail, highlighting increased activity as the interstellar comet moves through the inner solar system.
Auroras may be visible from Alaska to Illinois as an incoming coronal mass ejection could spark severe geomagnetic storm conditions overnight.
"Astronomers have wanted to spot a coronal mass ejection on another star for decades. We’ve now managed to do this for the first time."
