On Tuesday, the Chan Zuckerberg Initiative (CZI) announced that it intends to "observe, measure, and analyze any biological process throughout the human body - across spatial scales and in real-time." To achieve its goal of curing and preventing biological diseases, the organization will be donating $3.4 billion towards developing a variety of new institutions, as well as new research and technologies. The venture will span over 10 years.

A spokesperson for CZI, Jeff MacGregor, said that the organization will be giving $500 million over the next 15 years to develop a new artificial intelligence-focussed institution at Harvard University. This new institution will be named after Zuckerberg's mother, Karen Kempner Zuckerberg.

The first of the three asteroids that will be approaching Earth has been dubbed 2016 TR54, and according to NASA's database, it will pass by Earth on December 24, at 6:30 a.m. UTC. The asteroid is estimated to be anywhere between 328 and 754 feet in diameter and will be passing Earth at a speed of 34,700 miles per hour at a distance of four million miles, or around 17 times the distance between the Earth and the Moon.

The next asteroid that will pass by Earth is called 2018 AH, and is estimated to be slightly smaller than 2016 TR54 at a diameter of anywhere between 254 and 623 feet. 2018 AH is expected to have its closest approach on December 27 at 2:40 p.m. UTC (9:40 a.m. ET) at a speed of 28,400 miles per hour, at a distance of 622,800 miles, which is just over double the distance between the Earth and the Moon.

Rare solar eclipse photographed from deep space 1 million miles away

Jak Connor | Dec 9, 2021 12:34 AM CST

Many people missed out on the only total solar eclipse for 2021, but an observatory located one million miles out in deep space certainly didn't.

The only total solar eclipse for 2021 was only visible to those that were in Antarctica or in the Southern Ocean on Saturday, December 4. If you were located anywhere else you would have only seen a partial solar eclipse, or nothing at all. The remote locations to see the totallity of the solar eclipse didn't stop some resaerchers and photographers, who ventured out to the Union Glacier to take these photographs.

The photographers stationed on Union Glacier weren't the only cameras involved in the event, as NOAA's Deep Space Climate Observatory (DISCOVR) that's located 950,000 miles away from Earth in deep space had its camera pointed at the planet. The observatory was tracking the shadow of the solar eclipse as it passed over Earth and snapped an image using the Earth Polychromatic Imaging Camera (EPIC) built by NASA.

Alien world discovered, pushes the scientific understanding of planets

Jak Connor | Dec 9, 2021 12:02 AM CST

A team of astronomers has located a planet in a star system that previously wasn't thought to be able to host stars.

The two-star system is located approximately 325 light-years away from Earth within the constellation Centaurus. The system is called b Centauri and measures in at six times the mass of our Sun, which makes it the largest star system to have a planet orbiting it. Up until now, astronomers only found planets orbiting stars that were maximum three times the mass of our Sun. The discovery of this planet has expanded astronomers' knowledge of where its possible planets can form.

"B-type stars are generally considered as quite destructive and dangerous environments, so it was believed that it should be exceedingly difficult to form large planets around them," said Markus Janson, an astronomer at Stockholm University, Sweden and first author of the new study.

Scientists have made rigid crystals stretchy in a new study

Adam Hunt | Dec 8, 2021 6:30 AM CST

In a new study published in the journal Chem, researchers have modified crystalline structures to make them stretchy.

Chenfeng Ke, Assistant Professor of Chemistry at Dartmouth College, and his research team have designed carbon-based, porous crystals that can stretch to more than double their length.

"Picture a diamond that behaves like a rubber band," said Ke.

Porous organic frameworks are built from light organic elements like carbon, oxygen, and nitrogen. They form lattice structures with pores forming in the spaces between atoms, which means they can be used as filters for certain pollutants in fluids that can pass through the structure.

Radio signals detected from distant stars may indicate hidden planets

Adam Hunt | Dec 8, 2021 5:30 AM CST

With the most powerful radio antenna on Earth, researchers from the University of Queensland have detected radio signals from distant stars.

Radio signals detected from distant stars may indicate hidden planets 01

Dr. Benjamin Pope of the University of Queensland and colleagues from the Dutch national observatory ASTRON have been using the Low-Frequency Array (LOFAR) in the Netherlands to observe radio waves emanating from distant stars. These waves suggest the existence of unknown planets orbiting these stars.

"We've discovered signals from 19 distant red dwarf stars, four of which are best explained by the existence of planets orbiting them. We've long known that the planets of our own solar system emit powerful radio waves as their magnetic fields interact with the solar wind, but radio signals from planets outside our solar system had yet to be picked up. This discovery is an important step for radio astronomy and could potentially lead to the discovery of planets throughout the galaxy," said Dr. Pope.

NASA's new Sentry-II near-Earth asteroid monitoring system goes live

Adam Hunt | Dec 8, 2021 5:00 AM CST

NASA has developed a new near-Earth asteroid impact monitoring algorithm dubbed Sentry-II to help defend Earth against future asteroid threats.

Survey telescopes have identified nearly 28,000 near-Earth asteroids (NEAs) to date, with additional NEAs expected to be discovered and added at a rate of roughly 3,000 per year. With advances in survey telescope technology, this rate will likely increase. In response to the potential threat posed by these asteroids to Earth, NASA has developed Sentry-II, an asteroid impact monitoring algorithm that has just gone online.

The Center for Near-Earth Object Studies (CNEOS), managed by NASA's Jet Propulsion Laboratory (JPL) in Southern California, calculates the orbit of every known NEA, creating impact hazard assessments for NASA's Planetary Defense Coordination Office (PDCO). To do so, CNEOS has used Sentry software developed by JPL in 2002.

On December 6th, NASA recovered the final instrument aboard Hubble, the Space Telescope Imaging Spectrograph. The previous instrument to be recovered was the Cosmic Origins Spectrograph on November 28th, and before that the Wide Field Camera 3 and Advanced Camera for Surveys on November 22rd and November 7th respectively.

Hubble initially went into safe mode on October 25th in response to the loss of internal synchronization messages. As NASA has worked to bring the scientific instruments back online, no synchronization message issues have been detected since November 1st.

Mysterious 'house' on far side of the Moon photographed by rover

Jak Connor | Dec 8, 2021 3:02 AM CST

A rover exploring the surface of the Moon has snapped an image of what appears to be a mysterious "house", or "hut" object.

The image comes from an affiliated Chinese media channel called "Our Space", that details the rover Yutu 2 that first landed on the far side of the Moon back in January 2019. According to the post, the Yutu 2 rover spotted the object on the horizon while it was driving across the Von Karman crater last month, and sent back images of the object to the China National Space Administration (CNSA).

Space.com reports that the name "mystery hut" or "house" is currently being used as a placeholder name until the rover can identify what the object is. Additionally, the publication also points out that the object is most likely not a hut of any kind, and is more likely to be a large boulder that has been created from an impact event such as an asteroid. Yutu 2 is only 262 feet away from the object and will make its way over to inspect it over the next two to three months.
