Icy worlds speckle our solar system — from Jupiter's moon Europa to Saturn's moon Enceladus , scientists have been investigating these alien worlds, discovering subsurface oceans hidden under their icy crusts. Now, researchers have turned their gaze to the moons orbiting Uranus, searching for secret oceans.
In a new study not yet published, presented at the Dec. 15 AGU's Fall Meeting 2020, researchers led by Benjamin Weiss, a planetary scientist at the Massachusetts Institute of Technology, have developed a method for future missions to confirm the existence of subsurface oceans on worlds like the moons of Uranus. With this work, the team also hopes to further our understanding and knowledge of potentially habitable worlds.

Mysterious object orbiting Earth is 1966 rocket, not asteroid - al.com
FILE - This Sept. 20, 1966 photo provided by the San Diego Air and Space Museum shows an Atlas Centaur 7 rocket on the launchpad at Cape Canaveral, Fla. A mysterious object temporarily orbiting Earth is the Centaur upper stage of this 54-year-old rocket, not an asteroid after all, astronomers confirmed Wednesday, Dec. 2, 2020. Observations by a telescope in Hawaii clinched its identity, according to NASA's Jet Propulsion Laboratory in Pasadena, California.
The object was classified as an asteroid after its discovery in September. But NASA's top asteroid expert, Paul Chodas, quickly suspected it was the Centaur upper rocket stage from Surveyor 2, a failed 1966 moon-landing mission. Size estimates had put it in the range of the old Centaur, which was about 32 feet (10 meters) long and 10 feet (3 meters) in diameter.

Winter solstice 2020: Behold, the view of Earth's longest night from space | Space
Today marks the winter solstice in the Northern Hemisphere — the shortest day (and longest night) of the year and the beginning of the winter season. The event, which also marks the start of summer in the Southern Hemisphere, is caused by Earth's axial tilt and the planet's motion as it orbits around the sun at the center of our solar system.
Earth doesn't sit upright as it circles the sun. Instead, it orbits on its axis at a tilt of 23.5 degrees. Our planet's Northern and Southern hemispheres take turns with sunlight, trading places when it comes to seasons. So, on the winter solstice, the planet's Northern Hemisphere is turned as far away from the sun as it ever is.

Paxos brought in $142 million in its latest funding round . The crypto service provider with big-name clients including PayPal, Credit Suisse, Societe Generale and Revolut now looks to double its workforce and expand its suite of products. "We are not a unicorn," CEO Charles Cascarilla said, but it is a big fish going after a OCC-granted national bank license .
If Axions Explain Dark Matter, it Could be Possible to Detect Them Nearby Neutron Stars -
Physicists have looked beyond the standard model of particle physics for possible candidates, and one that has looked promising is known as the axion. Axions were first proposed in the 1970s to deal with a problem of symmetry in particle physics. As Emmy Noether first pointed out, symmetry is fundamental to the nature of physics. In particle physics, there are three important symmetries: charge, parity, and time.
Time symmetry deals with how interactions look the same forwards and backward in time. Imagine two billiard balls colliding on a pool table. If you saw a video of the collision, it would be difficult to determine whether the video was reversed without some other clue. Billiard balls obey time symmetry. Charge symmetry deals with how charges interact. Two positive charges repel each other, but so do two negative charges.
Exploring new worlds in virtual reality | ASU Now: Access, Excellence, Impact
Inside the pod, as your avatar, you're immersed in a new world. You're working in a virtual laboratory with a plethora of fictional animal species that function based on biological laws. You can explore, discover, observe and experience numerous hands-on problem-solving tasks that you can't dream of or do within a traditional classroom.
This isn't a game; it's ASU's new virtual reality immersive biology curriculum called Dreamscape Learn, made possible through a partnership with Dreamscape Immersive. Based on the work of curriculum experts at ASU, students in the university and beyond will benefit from the new world order of education: VR immersive learning.
