NASA said Monday it has found new evidence of 219 planets outside our Solar System. Ten of those exoplanets appear to be similar to the size of the Earth and orbit their stars in the habitable zone. From a report: The new planets’ existence must still be double-checked. But Kepler’s latest haul — which includes a planet that is only slightly larger than Earth and receives the same amount of energy from its sun as Earth — is the latest triumph for Kepler, which has spotted roughly 80 percent of the planets orbiting stars other than our sun. Because of their potential for hosting life, the 10 Earth-size planets are the most glamorous of the newly announced planets from Kepler. But those 10 were joined by an additional 209 more garden-variety planets that are unlikely to be hospitable to life because they are too gassy, too hot, too cold or otherwise unlike the only known planet to host life: Earth.

New Evidence That All Stars Are Born In Pairs

InfiniteZero shares a report from Phys.Org: Did our sun have a twin when it was born 4.5 billion years ago? Almost certainly yes — though not an identical twin. And so did every other sun-like star in the universe, according to a new analysis by a theoretical physicist from UC Berkeley and a radio astronomer from the Smithsonian Astrophysical Observatory at Harvard University. The new assertion is based on a radio survey of a giant molecular cloud filled with recently formed stars in the constellation Perseus, and a mathematical model that can explain the Perseus observations only if all sunlike stars are born with a companion. “We ran a series of statistical models to see if we could account for the relative populations of young single stars and binaries of all separations in the Perseus molecular cloud, and the only model that could reproduce the data was one in which all stars form initially as wide (more than 500 astronomical units) binaries,” said co-author Steven Stahler, a UC Berkeley research astronomer. “These systems then either shrink or break apart within a million years.” The study has been published in April on the arXiv server.

On June 3, SpaceX’s Falcon 9 rocket was placed into low-orbit for the sake of launching its Dragon spacecraft into their eleventh Commercial Resupply Services mission (CRS-11) to the International Space Station… Last week SpaceX shared on their Youtube channel the remarkable 4K UHD footage of the landing, and since many of us are not used to watching this kind of footage except for Sci-Fi movies or video games, the landing seems almost Hollywood-level surreal, especially since it happens so quickly and accurately. You can watch the video at 4k and 60 fps here if you happen to own a 4K TV or UHD PC monitor with the right hardware specs… The footage above isn’t SpaceX’s first 4K video of one of its launches. The company has also previously released other videos of even more impressive landings directly onto the surfaces of drone ships.
The article also reminds readers that “If you are by any chance looking to send something or someone out of space, Elon Musk’s company offers reasonable prices for their launching services, starting at $62 million for its Falcon 9 and $90 million for the Falcon Heavy.”

Has the 40-year Old Mystery of the ‘Wow!’ Signal Been Solved?

“Astronomers have confirmed that the Wow! signal, thought to be the most promising detection by SETI of alien life, was actually caused by a comet,” writes schwit1. New Atlas reports:

Last year, a group of researchers from the Center of Planetary Science proposed a new hypothesis that argued a comet might be the culprit. The frequency could be caused by the hydrogen cloud they carry, and the fact that they move accounts for why it seemingly disappeared. Two comets, named 266/P Christensen and P/2008 Y2 (Gibbs), happened to be transiting through that region of space when the Wow! signal was detected, but they weren’t discovered until after 2006. To test the hypothesis, the team made 200 radio spectrum observations between November 2016 and February 2017. Sure enough, 266/P Christensen was found to emit radio waves at a frequency of 1,420 MHz, and to double check, the researchers moved their radio telescope by one degree. As expected, the signal vanished, and only returned when the telescope was trained back on the comet.

schwit1 quotes a report from Los Angeles Times: SpaceX will launch the Air Force’s X-37B experimental spaceplane later this year, in the military’s latest vote of confidence in the Elon Musk-led space company. This will be the first time SpaceX has launched the uncrewed robotic vehicle. United Launch Alliance, a joint venture between Boeing Co. and Lockheed Martin Corp., has launched the spaceplane’s previous four missions atop one of its Atlas V rockets. The Air Force Rapid Capabilities Office, which is responsible for the X-37B’s experimental operations, said it was “very excited” for the fifth flight, which will test how special electronics and heat pipes will fare during a long-duration space mission. The Air Force has two of the spaceplanes, which look like miniature versions of the space shuttle and are known officially as X-37B Orbital Test Vehicles. The first X-37B was launched in 2010.

Astronomers have observed for the first time ever a distant star warp the light of another star, “making it seem as though the object changed its position in the sky,” reports The Verge. The discovery is especially noteworthy as Albert Einstein didn’t think such an observation would be possible. From the report: These events require stars that are very far apart to line up perfectly. That’s why Einstein once wrote that “there is no hope of observing this phenomenon directly.” Our telescope technology has become far more sophisticated than in Einstein’s day — which is what allowed us to observe something he thought we’d never see. In 2014, a group of astronomers using NASA’s Hubble Space Telescope spotted a rare type of microlensing, when a dense white dwarf star passed in front of another star thousands of light-years away. The stars weren’t exactly aligned, but they were close enough that the white dwarf made it seem like the background star performed a small loop in the sky. “It looks like the white dwarf pushed it out of the way,” Terry Oswalt, an astronomer at Embry-Riddle Aeronautical University who was not involved in this discovery but wrote a perspective piece in Science, tells The Verge. “That’s not what happened, of course. It just looks like that.” The astronomers also used the apparent movement of the background star to measure the mass of the passing white dwarf, a novel technique detailed in a paper published today in Science. And they say this isn’t the last time they’ll make measurements like this either. Now that they’ve figured out how to spot these kinds of lensing events, they’re hoping to find even more with new ground- and space-based telescopes that are coming online soon.

Science_afficionado writes: An international team of astronomers has discovered a planet like Jupiter zipping around its host star every day and a half, boiling at temperatures hotter than most stars and sporting a giant, glowing gas tail like a comet. From a report via Vanderbilt University: “With a day-side temperature peaking at 4,600 Kelvin (more than 7,800 degrees Fahrenheit), the newly discovered exoplanet, designated KELT-9b, is hotter than most stars and only 1,200 Kelvin (about 2,000 degrees Fahrenheit) cooler than our own sun. In fact, the ultraviolet radiation from the star it orbits is so brutal that the planet may be literally evaporating away under the intense glare, producing a glowing gas tail. The super-heated planet has other unusual features as well. For instance, it’s a gas giant 2.8 times more massive than Jupiter but only half as dense, because the extreme radiation from its host star has caused its atmosphere to puff up like a balloon. Because it is tidally locked to its star — as the moon is to Earth — the day side of the planet is perpetually bombarded by stellar radiation and, as a result, it is so hot that molecules such as water, carbon dioxide and methane can’t form there.” The findings have been published in the journal Nature.
