Einstein's general theory of relativity states that the curvature of space-time causes gravity. But zoom out to enormous scales like clusters of galaxies spanning billions of light years across, and the laws of Einstein's gravity theory appear to change. A 1% adjustment may not sound like a big deal, but it's enough to suggest that Einstein's theory may need a rethink. Now, with this cosmic glitch, there's a new explanation on the table. NASA/CXC/Univ of Missouri/M.Brodwin et al; NASA/STScI; JPL/CalTechThe fact that this cosmic glitch could potentially help astronomers resolve the Hubble tension is a good sign that it may truly exist.

Using telescopes capable of detecting X-rays, a team of astronomers has for the first time observed this area — called the “plunging region” — in a black hole about 10,000 light-years from Earth. The study’s findings could help astronomers better understand the formation and evolution of black holes. One thing that’s missing from the study is an actual image of the black hole, because it is too small and far away. But another team of Oxford researchers is working on something even better than a picture: the first movie of a black hole. “For example, it can be used to measure the rotation rate of the black hole,” said Reynolds, who was not involved in the study.

But the kicker is that this giant void shouldn't exist in the first place. For example, some people have correctly argued that such a void shouldn't exist in the standard model, which is true. Cosmologists have a value, called the Hubble constant, which they use to help describe how fast the universe's expansion is accelerating. The Hubble constant should be the same value wherever you look, whether it's close by or very far away. NASA/JPL-CaltechAstronomers can't agree on what's causing this discrepancy in the Hubble constant, and the contention has become known as the Hubble tension.

Ancient DNA pulls back curtain on mysterious empire

Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter. Analysis of ancient DNA recovered from human remains has illuminated the traits and ancestry of historic individuals — be it a mummified iceman, Chinese emperor or legendary composer. The origins of the empire and its people remained obscure until a landmark April 2022 study found they hailed from the Mongolian steppe.

CNN —Close flybys of Io, one of Jupiter’s moons and the most volcanically active world in our solar system, have revealed a lava lake and a towering feature called “Steeple Mountain” on the moon’s alien surface. “We also got some great close-ups and other data on a 200-kilometer-long (127-mile-long) lava lake called Loki Patera. Juno detected the mountain with the help of the sun shining on Io’s surface, which created dramatic shadows that revealed a very sharp peak. NASA/JPL-Caltech/SwRI/MSSSAs an outdoors enthusiast, Bolton joked that Io’s Steeple Mountain should be one of the solar system’s skiing and snowboarding destinations. The mission team used Juno’s Microwave Radiometer instrument to create maps of Io’s surface, showing how incredibly smooth it is.

Voyager 1’s flight data system collects information from the spacecraft’s science instruments and bundles it with engineering data that reflects its current health status. But since November, Voyager 1’s flight data system had been stuck in a loop. By investigating the readout, the team determined the cause of the issue: 3% of the flight data system’s memory is corrupted. Members of the Voyager flight team celebrate after receiving the first coherent data from Voyager 1 in five months at NASA's Jet Propulsion Laboratory on April 20. And younger engineers are coming onto the Voyager team and contributing their knowledge to keep the mission going.”

CNN —NASA is seeking innovative methods that could help retrieve samples collected by the Perseverance rover on Mars in the future. The original design for the Mars Sample Return program, a partnership between NASA and the European Space Agency, was a complex one. Reviews of the program have recommended that the Mars Sample return should not cost more than $5 billion to $7 billion, Nelson said. “Mars Sample Return will be one of the most complex missions NASA has ever undertaken. “We are operating from the premise that this is an important national objective that we return the samples,” Nelson said.

NASA's Perseverance Mars rover is collecting samples that could be evidence of ancient alien life. But NASA's Mars Sample Return mission to bring them to Earth will now cost $11 billion and take two decades. NASA/JPL-Caltech/ASUNASA's original proposal for the Mars Sample Return is "mind-bendingly complicated," David Parker, director of space exploration at the European Space Agency, said in 2021. AdvertisementAn illustration shows a concept of how NASA's Mars Sample Return mission would launch Perseverance's samples from the surface of Mars.

Editor’s note: Follow along with CNN’s live updates of the total solar eclipse. Special eclipse momentsWhile totality is considered to be the most exciting part of a total solar eclipse, there are other special phases to watch for before the big moment arrives. Amateur astronomers prepare to watch a total solar eclipse in Mazatlan, Mexico, on Monday. After the total solar eclipse ends, it’s a bit of a wait for the next such celestial sightings in the United States. Those living in Alaska will catch a glimpse of a total solar eclipse on March 30, 2033, and a partial solar eclipse will shine over most of the US during that event.

CNN —When NASA’s Europa Clipper aims to launch on its highly anticipated mission to an icy moon in October, the spacecraft will carry a unique design etched with names, poetry and artwork symbolizing humanity. This latest mission is headed to Jupiter’s moon Europa, one of several lunar ocean worlds considered to be the best places to search for life beyond Earth. NASA/JPL-CaltechA planetary legacyEarly NASA probes such as Pioneer 10 and Voyager have continued to inspire the artwork that travels aboard other planetary science missions. “The content and design of Europa Clipper’s vault plate are swimming with meaning,” said Lori Glaze, director of NASA’s Planetary Science Division, in a statement. “We’ve packed a lot of thought and inspiration into this plate design, as we have into this mission itself,” said Robert Pappalardo, project scientist at JPL, in a statement.

NASA's Juno mission found that Jupiter's icy moon Europa produces 1,000 tons of oxygen every 24 hours. That's enough oxygen to keep a million people alive for a day, NASA reported this week. Some of it may get stuck in the ice, some may escape to space, and some may travel downward into Europa's subsurface ocean. NASAWhat NASA's Juno mission has done is shed more light on the total amount of oxygen that Europa's surface generates. Measuring oxygen on EuropaTo measure how much oxygen Europa's surface generates, scientists used the Jovian Auroral Distributions Experiment (JADE) instrument on board Juno.

This encounter was the second in a set of two close fly-bys designed to provide new insight into the fiery phenomena that lurk beneath Io's surface. The twin flybys are designed to provide new insight into how Io’s volcanic engine works and whether a global magma ocean exists under Io’s rocky surface.

CNN —After completing 72 historic flights on Mars over three years, NASA’s Ingenuity helicopter mission has ended. NASA/JPL-CaltechThe NASA mission team only expected the chopper to carry out five test flights in 30 days. The chopper flew over areas of scientific interest to capture images and help the mission team determine Perseverance’s next targets for detailed analysis. “The Mars helicopter would have never flown once, much less 72 times, if it were not for the passion and dedication of the Ingenuity and Perseverance teams. History’s first Mars helicopter will leave behind an indelible mark on the future of space exploration and will inspire fleets of aircraft on Mars — and other worlds — for decades to come.”

CNN —The disappearing “magic islands” on Saturn’s largest moon Titan have intrigued scientists since NASA’s Cassini mission spotted them during flybys a decade ago. Titan, larger than both our moon and the planet Mercury, is the only moon in our solar system with a thick atmosphere. The sea is 50% larger than Lake Superior and is made up of liquid methane, ethane and nitrogen. An artist's illustration shows a lake at the north pole of Saturn's moon Titan, including raised rims spied by Cassini. Liquid methane slowly seeps into the frozen clumps, eventually causing them to disappear from view.
