Curiosity is continuing to make the most of the new year - both on Earth and on Mars which recently entered Mars Year 37, only a few days before the new year on Earth. After a successful drive along the slope below the Marker Band, we're ready for a full weekend.

Little 'hurricanes' that form in the discs of gas and dust around young stars can be used to study certain aspects of planet formation, even for smaller planets which orbit their star at large distances and are out of reach for most telescopes.
Researchers from the University of Cambridge and the Institute for Advanced Study have developed a technique, which uses observations of these 'hur IXPE Team Profile; LASP at Colorado-Boulder

As NASA's Imaging X-ray Polarimetry Explorer mission explores black holes, neutron stars, and other cosmic phenomena - helping to answer fundamental questions about extreme space environments - it relies on the mission operations team at the Laboratory for Atmospheric and Space Physics, or LASP.

When deep learning models are deployed in the real world, perhaps to detect financial fraud from credit card activity or identify cancer in medical images, they are often able to outperform humans.
But what exactly are these deep learning models learning? Does a model trained to spot skin cancer in clinical images, for example, actually learn the colors and textures of cancerous tissue, or New discovery of sunscreen-like chemicals in fossil plants reveals UV radiation played a part in mass extinction events

New research has uncovered that pollen preserved in 250 million year old rocks contain compounds that function like sunscreen, these are produced by plants to protect them from harmful ultraviolet (UV-B) radiation. The findings suggests that a pulse of UV-B played an important part in the end Permian mass extinction event.

We all know the saying that there is strength in numbers. The next revolution in space technology could be the use of swarms of tiny spacecraft, called CubeSats, that work together to achieve things greater than what any lone spacecraft can. CubeSats, assemble!

NASA is preparing for the return of multiple science experiments from the International Space Station in the hopes they might further aid mankind's future exploration of space.
A Dragon spacecraft that docked with the station on Nov. 27 is scheduled to return to Earth and splash down off the eastern coast of Florida on Jan. 9, NASA said in a press release.

A retired NASA satellite is expected to fall to Earth on Sunday after spending nearly 40 years in space, space officials said Friday.
The U.S. Defense Department has predicted that the 5,400-pound Earth Radiation Budget Satellite will reenter the atmosphere sometime within a 17-hour window of 6:40 p.m. EST on Sunday, NASA said in a statement.

Once in 50,000-year comet may be visible to the naked eye
Saturday, 07 January 2023 09:55 Write a comment
A newly discovered comet could be visible to the naked eye as it shoots past Earth and the Sun in the coming weeks for the first time in 50,000 years, astronomers have said.
The comet is called C/2022 E3 (ZTF) after the Zwicky Transient Facility, which first spotted it passing Jupiter in March last year.
After traveling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1.
It will be easy to spot with a good pair of binoculars and likely even with the naked eye, provided the sky is not too illuminated by city lights or the Moon.
The comet "will be brightest when it is closest to the Earth", Thomas Prince, a physics professor at the California Institute of Technology who works at the Zwicky Transient Facility, told AFP.
