When a beam of light hits a super-shiny object like a mirror, it reflects off it in a very particular way.Photograph: Rhett AllainFor both of them, their light hits the mirror at the same angle that their light also reflects from the mirror—but in the opposite direction.
This new research, led by Deborah Domingue at the Planetary Science Institute in Tucson, Arizona, and Yasuhiro Yokota at Kochi University in Japan, sheds light on Ryugu’s complex structure, revealing it to be a dark, weathered pile of rubble tumbling in space, different from anything seen on the surface of the Earth.
Today, Google announced a new 3D time-lapse feature in its Google Earth platform.Google says the time-lapse feature draws from 20 petabytes of satellite imagery, combined to create a 4.4-terapixel video (that's 4.4 million megapixels) that maps to the surface of the globe.
Now, a study of the rocks from the Australian Outback by Tusch, Münker and their co-authors, published in Proceedings of the National Academy of Sciences, has captured “a snapshot” of the advent of plate tectonics, said Alan Collins, a geologist at the University of Adelaide in Australia.
A new study from a Jet Propulsion Laboratory group led by Társilo Girona highlights the possibility that presently available satellite data could provide an entirely new way to warn of eruptions .Heat is obviously a relevant parameter for volcanic activity, but it can be quite variable at the individual spots where you might set up a thermometer.
On February 9, the United Arab Emirates’ Hope spacecraft is expected to enter orbit around Mars after a six-month, 300-million-mile journey from Earth.China’s space agency has been quiet about its plans for visiting the Red Planet, but the craft is expected to attempt a landing shortly after it achieves orbit.
You might not spend much time imagining life on a cube, but mathematicians do: They study what travel looks like on all kinds of different shapes.On a sphere, straight paths follow “great circles,” which are geodesics like the equator.

NIWA forecasters say a marine heatwave is forming around parts of New Zealand after sea surface temperatures (SSTs) warmed considerably last month.
The reason that both storms have been so strong and so late is that both the Pacific and Atlantic oceans have stayed warm this year, says John Knaff, a meteorologist at NOAA’s Cooperative Institute for Research in the Atmosphere at Colorado State University.

A network of state-of-the-art tsunami buoys is being deployed from New Zealand up into the Pacific to keep communities safer.Every 15 seconds the BPR records the height of the ocean above it and sends that information to the surface buoy once an hour.

The Coleman certainly has its flaws, and I'll get to those, but let's pause here and talk about an industry-wide problem: the lack of easy recycling for the camp fuel canisters.
The skycrane is outfitted with eight small engines that start firing when the rover is about half a mile up to rapidly slow its fall to just a few miles per hour.“These particular engines are actually a derivative of the original engines developed for Viking landers in the early ’70s, but we've made very significant upgrades,” says Fred Wilson, a propulsion expert at Aerojet Rocketdyne, the company that made the propulsion system for the Perseverance landing system.
Elsewhere in the world’s oceans, much of the seafloor sediment is organic matter.There’s no upwelling and much less life at the surface, so much less organic matter is sinking to the seafloor to form sediment.
A heat dome “is really just sort of a colloquial term for a persistent and/or strong high-pressure system that occurs during the warm season, with the end result being a lot of heat,” says climate scientist Daniel Swain of UCLA’s Institute of the Environment and Sustainability.
When she’s not hunting for ancient life on other planets, Bosak studies the earliest life on our own, a process she says is analogous to what Perseverance will be doing on Mars.
Best known for innovative, tablet-like hardware designs, Microsoft has expanded its Surface line over the years and now offers a full family of computers, from a standard laptop to a giant desktop.Last year, Microsoft added a 15-inch model to its Surface Laptop line.
The ruins are deep underground, but a team of archaeologists from the University of Cambridge and Ghent University in Belgium have used ground-penetrating radar (GPR) to map the complete city.
“That bubble actually acts as like a sponge for tiny particles like sea salt, viruses, bacteria, and—potentially—plastics, as it comes up through the water column,” says University of Strathclyde microplastic researcher Deonie Allen, co-lead on the new research.
The puzzling, fascinating surface of Jupiter's icy moon Europa looms large in this newly-reprocessed color view, made from images taken by NASA's Galileo spacecraft in the late 1990s.Photograph: NASA/JPL-Caltech/SETI InstituteOur final image in this series shows more chaos terrain in a region called Chaos Near Agenor Linea.

The word “corona” has Latin roots, meaning essentially “crown.” The solar corona is the outermost region of the Sun’s atmosphere, a hazy aura made of colder plasma that is released from the surface of the star.
