Black holes really are giant fuzzballs, a new study says. The study attempts to put to rest the debate over Stephen Hawking's famous information paradox, the problem created by Hawking's conclusion that any data that enters a black hole can never leave. This conclusion accorded with the laws of thermodynamics, but opposed the fundamental laws of quantum mechanics.

China has approved the fourth phase of its lunar exploration program, including a basic model of a research station built on the moon over the coming decade, according to the China National Space Administration.
Wu Yanhua, deputy director of the administration, said China would carry out lunar exploration in the future Chang'e-6, Chang'e-7 and Chang'e-8 missions.

The next flight on Mars marks the first of 2022 and the nineteenth for NASA's Ingenuity Mars Helicopter. The current mission goal is to reach the Jezero river delta to aid the Perseverance rover in path planning and scientific discovery.

Tosol, Curiosity woke up in a new mapping quadrant, Roraima. The Roraima quadrant is named after the northern-most state of Brazil and Mount Roraima, which is the highest peak in the Pakaraima mountains which sits between Brazil, Venezuela, and Guyana.
The terrain in the Roraima region on Earth looks somewhat similar to the area Curiosity is in - with flat-topped hills and some steep slope China's Mars orbiter captures series of selfies using remote camera

The China National Space Administration released photos on New Year's Day, of its Mars orbiter circling high above the Red Plant.
The selfies were taken by a small camera which was deployed by the Tianwen 1, capturing images of the orbiter and sending them back to it via a WiFi connection.
The photos were then relayed back to Earth where they were published by China's space agenc How scientists designed the orbit of the Chang'E 5 mission

In the early morning of November 24, 2020, the Chang'E 5 lunar probe was launched from the Wenchang Space Launch Center and successfully executed a 23-day journey of lunar sample return (LSR) mission.

The Quandrantid meteor shower helped kick off the first workday of the new year on Monday, with the peak somewhat tough to see in North America - but the rest of the world got a good show.
The "Quads" as they are nicknamed, are slated to peak around 4 p.m. EDT (2100 GMT) on Monday, according to Margaret Campbell-Brown and Peter Brown in the 2022 version of the Observer's Handbook of th Asteroid 'Apophis' predicted to skim dangerously close to Earth in 2029

The Transiting Exoplanet Survey Satellite, TESS, was launched in 2018 with the goal of discovering small planets around the Sun's nearest neighbor stars. TESS has so far discovered 172 confirmed exoplanets and compiled a list of 4703 candidate exoplanets. Its sensitive camera takes images that span a huge field of view, more than twice the area of the constellation of Orion, and TESS has also as Kerstin Perez is searching the cosmos for signs of dark matter

Kerstin Perez is searching for imprints of dark matter. The invisible substance embodies 84 percent of the matter in the universe and is thought to be a powerful cosmic glue, keeping whole galaxies from spinning apart. And yet, the particles themselves leave barely a trace on ordinary matter, thwarting all efforts at detection thus far.

Real-time alert system heralds new era in fast radio burst research

McGill University scientists have developed a new system for sharing the enormous amount of data being generated by the CHIME radio telescope in its search for fast radio bursts (FRBs), the puzzling extragalactic phenomenon that is one of the hottest topics in modern-day astronomy.
It is not uncommon for the CHIME/FRB project to pinpoint several FRB events in a single day of operation as it sifts through nearly 1 million gigabytes of data gathered by the telescope. With the new data sharing system, which uses Virtual Observatory Event (VOEvent), a standardized language for reporting astronomical events, key details about each FRB that CHIME detects can now be sent in real time to observatories all over the world, allowing them to train their instruments on the source and gather further clues towards unraveling the mystery of FRBs.
"The enormous volume of data that CHIME/FRB generates and the large number of new FRBs that it detects each day is like a gold mine for a community that is eager to point every kind of telescope that exists at the next FRB," says Andrew Zwaniga, lead developer of the CHIME/FRB VOEvent Service and a research assistant in the Department of Physics at McGill.
Webb telescope fully deploys sunshield in mission milestone

The James Webb Space Telescope fully deployed its tennis-court sized sunshield Tuesday, a critical milestone for the success of its mission to study every phase of cosmic history, NASA said.
"All five layers of the sunshield are fully tensioned," said an announcer at the observatory's control center in Baltimore, where team members cheered, a live feed showed.
The 70-foot (21 meter) long, kite-shaped apparatus acts like a parasol, ensuring Webb's instruments are kept in the shade so they can detect faint infrared signals from the far reaches of the Universe.

The Webb team has completed tensioning for the first three layers of the observatory's kite-shaped sunshield, 47 feet across and 70 feet long.
The first layer—pulled fully taut into its final configuration—was completed mid-afternoon.
The team began the second layer at 4:09 pm EST today, and the process took 74 minutes. The third layer began at 5:48 pm EST, and the process took 71 minutes. In all, the tensioning process from the first steps this morning until the third layer achieved tension took just over five and a half hours.
These three layers are the ones closest to the Sun. Tensioning of the final two layers is planned for tomorrow.
"The membrane tensioning phase of sunshield deployment is especially challenging because there are complex interactions between the structures, the tensioning mechanisms, the cables and the membranes," said James Cooper, NASA's Webb sunshield manager, based at Goddard Space Flight Center.
