Astronomers spot light behind a black hole for the first time, reaffirming Einstein's theory of general relativity – TechSpot

Published

Something to look forward to: An international team of astronomers have observed light from behind a black hole for the first time. Future observatories, like the Advanced Telescope for High Energy Astrophysics (Athena) should provider even higher resolution images with much shorter observation times.1

Led by Stanford University’s Dan Wilkins, the team focused on a black hole that is 10 million times as massive as our sun and located 1,800 million light years away in a galaxy called I Zwicky.

Armed with the European Space Agency’s XMM-Newton and NASA’s NuSTAR space telescopes, the astronomers observed bright flares of X-ray light coming from around the black hole. The X-ray flares echoed off of gas that was falling into the black hole, and as the flares were subsiding, the telescopes were remarkably able to pick up smaller flashes of X-rays that were different “colors.” These were the echoes bouncing off the gas behind the black hole.

“Any light that goes into that black hole doesn’t come out, so we shouldn’t be able to see anything that’s behind the black hole,” Wilkins said. “The reason we can see that is because that black hole is warping space, bending light and twisting magnetic fields around itself,” he added.

The black hole’s gravitational pull is responsible for the warping of space.

This is the first time that astronomers have directly observed light from behind a black hole, and it also matches Einstein’s theory of general relativity, yet again confirming his predictions.

The team’s findings were recently published in the scientific journal Nature.

Elon Musk trolls Biden with Trump line over perceived Inspiration4 snub – CNET

Elon Musk, SpaceX founder and leading orbital travel agent, was feeling a bit slighted by the world’s most powerful man  after President Joe Biden failed to acknowledge the company’s landmark Inspiration4 mission that sent four civilians on a three-day trip in orbit of our planet. 

The flight was bankrolled by billionaire Jared Isaacman, who commanded the mission aboard a Crew Dragon capsule, alongside geologist Sian Proctor, data engineer Chris Sembroski and St. Jude Children’s Research Hospital employee Hayley Arceneaux. The quartet splashed down safely off the coast of Florida on Saturday.

The mission served as a fundraiser for St. Jude, with over $60 million raised from the public so far. Isaacman also pledged $100 million and Musk added $50 million.

When a Twitter user asked why the president hadn’t acknowledged Inspiration4, Musk hopped into the replies.

“He’s still sleeping,” the CEO wrote, in an apparent reference to Donald Trump’s favorite nickname for his former adversary, “sleepy” Joe Biden.

It seems fair to point out, as a number of other Twitter users have, that the president may have a few other things on his plate at the moment, like continuing to manage the response to a global pandemic, climate crisis and various national security threats. 

For what it’s worth, NASA administrator Bill Nelson, a Biden appointee, did offer his congratulations to the crew multiple times.

The White House did not immediately respond to a request for comment.

Inspiration4 is the latest in a string of pioneering space tourism missions this year. Richard Branson flew to the edge of space on the first fully crewed flight of his Virgin Galactic spaceplane in July. Nine days later, Amazon and Blue Origin founder Jeff Bezos cruised a bit higher with three other passengers on his New Shepard spacecraft. 

Unlike those flights, which lasted under 15 minutes each, the Inspiration4 mission was a much more complex venture that saw the four passengers performing scientific research during the multiple day flight as they orbited Earth over 40 times.

15 photos of last night's stunning 'Harvest Moon' over Victoria (PHOTOS) – Victoria Buzz

Last night, a full Harvest Moon peaked over Vancouver Island. 

Each year, the full moons in September and October fight for the title of “Harvest Moon”, with the full Moon that occurs nearest to the equinox winning the title.

If October’s full Moon occurs closer to the equinox than September’s, the September full moon is then referred to as the Corn Moon.

Since last night’s full moon peaked only two days before the fall equinox, it won the title of “Harvest Moon”.

The moon rose in the southeast and reached peak illumination just after sunset.

Thankfully, the weather was on our side for perfect viewing of the sky last night.

For those who may have missed it last night here are 15 photos of last night’s full Harvest Moon over Victoria:

NASA reorganizes to prepare for future missions to the Moon and Mars – Yahoo Movies Canada

Published

 on


As it moves towards returning to the Moon ideally sometime in 2024, NASA Administrator Bill Nelson is creating two new mission directorates. With the move, the agency is separating its existing Human Exploration and Operations Mission Directorate into the Exploration Systems Development Mission Directorate (ESDMD) and Space Operations Mission Directorate. NASA said it’s making the change in response to the increasing number of missions it’s conducting in low-Earth orbit, in addition to the plans it has for exploring deep space in the future.

It also announced who’s leading those units. Jim Free, a NASA veteran who has been with the space agency on and off since 1990, is the new associate administrator of ESDMD, while Kathy Lueders is taking on the equivalent position at the Space Operations Mission Directorate. Before becoming the first-ever woman to oversee human spaceflight at NASA, Lueders managed the Commercial Crew Program. As for what the two units will do, ESDMD will oversee the development of programs critical to Project Artemis and eventually manned spaceflight to Mars. Meanwhile, its counterpart will focus on launch operations, including those involving the International Space Station, with an eye towards Moon missions later.     

According to NASA, the reorganization is ultimately about looking forward to the next 20 years. The new structure will allow one unit to focus on human spaceflight while the other builds future space systems. In that way, the agency says there will be a constant cycle of development and operations to help it move forward with its space exploration goals.

“This reorganization positions NASA and the United States for success as we venture farther out into the cosmos than ever before, all while supporting the continued commercialization of space and research on the International Space Station,” Nelson said. “This also will allow the United States to maintain its leadership in space for decades to come.”
