☆ Someday, Earth Will Have a Final Total Solar Eclipse
▼ + stars: | 2024-04-09 | by ( Katherine Kornei | ) www.nytimes.com time to read: 1 min

The total solar eclipse visible on Monday over parts of Mexico, the United States and Canada was a perfect confluence of the sun and the moon in the sky. But it’s also the kind of event that comes with an expiration date: At some point in the distant future, Earth will experience its last total solar eclipse. That’s because the moon is drifting away from Earth, so our nearest celestial neighbor will one day, millions or even billions of years in the future, appear too small in the sky to completely obscure the sun. “We’ll only ever have annular eclipses,” said Noah Petro, a planetary scientist at NASA Goddard Space Flight Center, referring to “ring of fire” eclipses like the one that crossed the Americas in October. But putting an exact date on Earth’s final total solar eclipse is a serious computational challenge involving a variety of scientific disciplines.

A new image reveals powerful magnetic fields swirling around our hometown black hole, which is called Sagittarius A* (pronounced "A-star"). EHT had previously imaged its first black hole, Messier 87, in polarized light as well, though it doesn't look quite as striking:The Messier 87 supermassive black hole imaged in polarized light. EHT CollaborationSince both black holes have similar structures of magnetic fields, despite their immense difference in size, the EHT scientists now suspect that all supermassive black holes might have magnetic structures like this. Bigger black hole breakthroughs may be in storeFurther imaging with new innovative techniques and technologies could reveal even more secrets of supermassive black holes, both big and small.

The star, which is 3,000 light-years from Earth, is expected to burst in a gigantic explosion — known as a nova — in the coming months. This cosmic blast happens when a tiny white dwarf — the core of a dead star — is locked in the orbit of a giant red star. An artist's impression of a white dwarf exploding near a red giant. Nearby is an arc of four visible stars called the Corona Borealis.

☆ Mars could be creating 'giant whirlpools' deep within our planet's oceans
▼ + stars: | 2024-03-13 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +5 min

Mars may be 140 million miles away, but its gravitational pull could be impacting Earth's oceans. Scientists at the University of Sydney in Australia believe the red planet's tug is creating "giant whirlpools" in the oceans called eddies, which can shift the deep-sea floor. This, they claim, is part of a 2.4-million-year climate "grand cycle" on Earth that has been ongoing for at least 40 million years. The red planet's orbit and ours are locked in an intricate dance, and every so often, these line up so that Mars' gravitational pull on Earth is just a little more intense — this is called resonance. This information is crucial when refining models helping us see how our planet's intricate climate will progress over time.

NASA is shutting down a $2 billion project to test satellite refueling in space, it announced Friday, after the agency's auditor criticized the program's lead contractor, Maxar, citing "poor performance." The space agency said in a statement that the OSAM-1 — On-orbit Servicing, Assembly, and Manufacturing 1 — project was being discontinued after nearly a decade of work. NASA did not respond to CNBC's request for comment on how many personnel will be affected as a result of OSAM-1's cancellation. Maxar was taken private by private equity firm Advent International in May 2023 before being split into two businesses: Maxar Intelligence, focused on satellite imagery and analytics, and Maxar Space Systems, focused on spacecraft manufacturing. NASA's Goddard Space Flight Center in Maryland was leading the work on OSAM-1, with Maxar Space Systems as the project's prime contractor under multiple deals.

CNN —Mary Cleave, the NASA astronaut who in 1989 became the first woman to fly on a space shuttle mission after the Challenger disaster, has died at the age of 76, the space agency announced on Wednesday. “For me, space flight was great, but it was gravy on top of getting to fly in great airplanes,” she told NASA. Getting to orbitOn her first mission, flying on NASA’s Space Shuttle Atlantis in 1985, Cleave became the 10th woman to travel into space. Over the course of her two shuttle missions, Cleave spent more than 10 days in orbit. Cleave said she made the difficult decision to move on from the corps and NASA’s astronaut hub in Houston, taking a role at Goddard Space Flight Center in Maryland in 1991.

Lucy will visit nine additional space rocks through 2033, part of NASA’s broader effort to glean knowledge about our celestial neighborhood. “The Trojans are the last big population of objects that we have not yet seen close up,” said Thomas Statler, a NASA planetary scientist on the mission.

CNN —A spacecraft left behind by US astronauts on the lunar surface could be causing small tremors known as moonquakes, according to a new study. The lunar surface is an extreme environment, oscillating between minus 208 degrees Fahrenheit (minus 133 degrees Celsius) in the dark and 250 degrees Fahrenheit (121 degrees Celsius) in direct sun, according to a news release about the study. Marusiak was not directly involved in the study, though she did have contact with the authors as a fellow expert in lunar seismology. “Every lunar morning when the sun hits the lander, it starts popping off,” said study coauthor Allen Husker, a research professor of geophysics at Caltech, in a statement.
