CNN —Astronomers have observed a massive pair of jets releasing from a supermassive black hole 7.5 billion light-years from Earth. The megastructure spans 23 million light-years in length, making these black hole jets the largest ever seen, according to new research. Black hole jets can accelerate radiation and particles close to the speed of light, causing them to glow in wavelengths visible to radio telescopes. The massive black hole jets could help answer both. Martijn Oei (pictured), lead author of the new study, and his colleagues will continue their search for massive black hole jets.

Reptiles are astonishingly diverse, with extraordinary adaptations such as a tiny lizard in Costa Rica that has evolved a way to “scuba dive,” according to new research. Fantastic creaturesUsing the air bubble helps the anole to stay underwater longer, and the technique may help the tiny lizard hide from predators, researchers say. This ability allows the lizard to stay underwater for a prolonged period of time.

CNN —Engineers at NASA have successfully fired up a set of thrusters Voyager 1 hasn’t used in decades to solve an issue that could keep the 47-year-old spacecraft from communicating with Earth from billions of miles away. Currently the farthest spacecraft from Earth, Voyager 1 is about 15 billion miles (24 billion kilometers) away. Earlier this year, engineers spotted an issue when the fuel tube inside one of Voyager’s thrusters became clogged. Engineers switched again to the trajectory correction thruster set in 2018 when the second set also appeared clogged. Once the spacecraft has exhausted this thruster set, Voyager 1’s remaining option is the other already clogged set of attitude propulsion thrusters.

But Zijlstra, who was not involved with the new study, was the first to make the connection to SN 1181. The report suggested that SN 1181 might belong to the elusive Type Iax category of supernova due to the presence of this “zombie” white dwarf. That energy causes the sudden brightness of the supernova.”That massive collision might explain another curious aspect of the SN 1181 zombie star. “We theorize that the star reignited because SN 1181 was a Type Iax supernova, which is an incomplete explosion.

CNN —Data from a retired NASA mission has revealed evidence of an underground reservoir of water deep beneath the surface of Mars, according to new research. A team of scientists estimates that there may be enough water, trapped in tiny cracks and pores of rock in the middle of the Martian crust, to fill oceans on the planet’s surface. NASA's Mars Reconnaissance Orbiter took an image of InSight sitting on the Martian surface on February 2, 2019. “It’s certainly true on Earth — deep, deep mines host life, the bottom of the ocean hosts life.

The dissolved calcium carbonate then reacts with the CO2 in the water to form bicarbonate salts, locking the CO2 away. Adkins says that with a full-scale reactor, he aims to capture and store about half of a ship’s CO2 emissions. BAR Technologies/Cargill French company Airseas has developed the Seawing, which it says could help ships cut their carbon emissions by an average of 20%. A British company called Seabound, for example, makes a device that captures between 25% and 95% of a ship’s CO2 emissions. “We think that ships are actually going to be able to compete with underground CO2 storage,” he said.

So finding them in the atmosphere of Venus is interesting on that basis as well. But further analysis of that data by Clements’ team revealed weak traces of the molecule, reinforcing the theory. “To date, our analyses remain unchallenged in the literature,” said Mogul, who was not involved in the research of Clements’ team.

But the arrowhead-shaped specimen could help the Perseverance team unlock whether Mars was once a planet hospitable to life. Perseverance rover captured a 360-degree panorama of a region on Mars called “Bright Angel,” where a river flowed billions of years ago.

CNN —The Curiosity rover has made its most unusual find to date on Mars: rocks made of pure sulfur. “I think it’s the strangest find of the whole mission and the most unexpected,” said Ashwin Vasavada, Curiosity project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California. Previously, while exploring Mars, NASA’s Spirit rover broke one of its wheels and had to drag it along while using the other five to drive backward. And Vasavada says it’s what inspired the team to “look behind” the Curiosity rover — otherwise they wouldn’t have seen the crushed sulfur. To determine what process formed the sulfur rocks, the team considered nearby bedrock instead.

CNN —When a cruise liner-size asteroid comes within 19,883 miles (32,000 kilometers) of Earth on April 13, 2029, it won’t be alone. The European Space Agency has announced that its new Ramses spacecraft may accompany the asteroid Apophis before and after its safe, albeit rather close, pass of Earth. Astronomers think that an asteroid this large comes within such proximity to Earth only once every 5,000 to 10,000 years. In September 2022, NASA’s DART mission intentionally slammed a spacecraft into Dimorphos, a moonlet asteroid that orbits a larger parent asteroid known as Didymos. “The Ramses mission concept reuses much of the technology, expertise and industrial and science communities developed for the Hera mission,” said Paolo Martino, spacecraft manager for Hera who will also work on the Ramses mission, in a statement.

Meteoroids are space rocks that have broken away from larger rocky bodies and range in size from dust grains to small asteroids, according to NASA. “We’re interested in studying that on Mars because we can then compare and contrast what’s happening on Mars to what’s happening on the Earth.

Solar radiation hits MarsThe most extreme storm occurred on May 20 after an X12 flare released from the sun, according to data collected by the Solar Orbiter spacecraft currently studying the sun. The Curiosity rover, currently exploring Gale Crater just south of the Martian equator, took black-and-white images using its navigation cameras during the solar storm. But Mars lost its magnetic field billions of years ago, which means the planet has no shield from incoming energized solar particles. By tracing the data from multiple Martian missions, scientists were able to watch how the solar storm unfolded.

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.

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.
