Astronomers refer to systems such as these as " X-ray binaries". The star is estimated to be about half the size of the Sun, and the rings that are clearly seen in the image aren't visible in visible light, but are clear as day through X-ray vision as the material "glows". The space agency explains that the rings are caused by the black hole pulling material away from a companion star located within its approximate vicinity. So, what causes these rings to appear in the X-ray image? NASA explains on its website that the above image showcases rings around a black hole located in the binary system called V404 Cygni, that's located approximately 7,800 light-years from Earth. NASA has published a new image of a black hole using its Chandra X-Ray Observatory and the Neil Gehrels Swift Observatory. NASA's Perseverance rover will take its samples to the Sample Retrieval Lander, where a robotic arm provided by the European Space Agency (ESA) will load them into an ascent vehicle.Ĭontinue reading: NASA announces it will 'inspire' the world in 2033 (full post) NASA snaps jaw-dropping image of huge rings surrounding a black hole These two helicopters will provide a secondary capability to retrieve the Mars samples cached on the surface of Mars. NASA writes that the retrieval mission will include a craft called the Sample Retrieval Lander that will feature two sample recovery helicopters that will be designed off the helicopter currently sitting on the surface of Mars, Ingenuity. The space agency has taken to its blog to reveal its updated plan for retrieving the Mars samples, and according to NASA, it's coming to the end of its conceptual design phase. NASA is devising a plan to get those samples and more back on Earth. NASA's Perseverance rover, which landed in the Jezero Crater on February 18 2021, has been hard at work collecting Mars samples, and so far, it has collected 11 scientifically-compelling rock core samples along with one atmospheric sample. Overall, thinking on its own was rated between 3 to 4 on a 7-point scale of enjoyment.Ĭontinue reading: New study suggests putting devices down and to just enjoy thinking (full post) Russia plans to assemble its own space station, coming in 2028
The thinking group more greatly underestimated their actual enjoyment, and both groups reported similar enjoyment levels after their respective activities. One experiment saw a group of participants predict their enjoyment of a bout of thinking, and another predicted their enjoyment of checking the news online. The researchers found that in every scenario, participants enjoyed the experience more than they initially predicted. Multiple variations of the same experiment were performed, reducing the time to 3 minutes, removing visual stimulation by sitting participants in a dark, tented area or empty conference room, and more. Participants were made to sit alone for 20 minutes without any distractions such as smartphones, books, or being able to walk about, and to predict how much they would enjoy it beforehand. Researchers have conducted six experiments involving 259 participants, comparing how people expected to enjoy sitting around and thinking with how much they actually enjoyed the experience. However, 2013 CU83 is much larger, measuring roughly 600 feet (183 meters) across at its widest point.Ĭontinue reading: Two gigantic asteroids are headed for Earth this weekend (full post) New study suggests putting devices down and to just enjoy thinking
This distance is 18 times the average distance between the Earth and the Moon, compared to 7 times that distance for 2016 CZ31's close approach. 2013 CU83 won't come as close to Earth, only coming as close as 4,320,000 miles (6,960,000 km) from Earth. The second asteroid, 2013 CU83, will make its close approach to Earth at 23:37 UTC. 2016 CZ31 measures roughly 400 feet (122 meters) across, with a width comparable to the height of a 40-story skyscraper.
The asteroid orbits within the solar system and makes its closest pass by Earth every few years, with the next one due in January 2028. The first of the two asteroids is named 2016 CZ31 and will make its close approach at 23:02 UTC on Friday, missing the planet by about 1,740,000 miles (2,800,000 kilometers).
