The First Chinese Crew is Busy on their New Space Station

On Thursday, June 17th, China took another major step in its ongoing drive to become a superpower in space. Just two months after the core module of the Tiangong space station (literally, “Heavenly Palace”) was sent to orbit, the three astronauts that will be the station’s first crew launched to space. The mission, Shenzhou 12, lifted off atop a Long March-2F rocket at 09:22 p.m. on Wednesday evening local time (09:22 a.m. EDT; 06:22 a.m. PDT) from the Jiuquan launch center in the Gobi desert.

Virgin Galactic Wins FAA’s OK to Fly Space Passengers: Which Billionaire Will Go First?

Virgin Galactic says it’s received the Federal Aviation Administration’s go-ahead to fly customers on its SpaceShipTwo rocket plane, marking a significant step in a commercial rollout that could also feature dueling space billionaires.

The FAA’s clearance came in the form of an update to Virgin Galactic’s five-year-old commercial space transportation operator license, the company said in a news release. The upgrade was based on an analysis of the results from Virgin Galactic’s most recent suborbital test flight, conducted in May at Spaceport America in New Mexico.

Long-Awaited UFO Report Opens the Door Wider to Sharing Strange Aerial Sightings

After months of anticipation, U.S. intelligence experts have released a report citing 18 incidents since 2004 in which unidentified flying objects — or unidentified aerial phenomena, to use the Pentagon’s term — appeared to demonstrate breakthrough technologies.

The nine-page, unclassified version of the report doesn’t describe the incidents in detail, and doesn’t attribute them to aliens. But it suggests they’re not linked to existing U.S. military technologies.

The point of the report, produced by the Office of the Director of National Intelligence in response to a congressional mandate, is to assess the potential threat posed by the anomalous aerial phenomena reported by U.S. military fliers over the years, whether you call them UFOs or UAPs.

Intelligence experts said they didn’t have enough data to get a firm fix on the nature of 143 out of 144 UAP reports that were filed between 2004 and this March. The one case they said they could resolve “with high confidence” was attributed to a large, deflating balloon.

Their conclusion was that UAP sightings should get more attention.

Aliens in 2,034 Nearby Star Systems Could use the Transit Method to see Earth

For centuries, human beings have speculated about the existence of planetary systems (much like our own) orbiting other stars. However, it has only been in the past few decades that scientists have been able to detect and study these distant worlds. To date, astronomers have used various methods to confirm the existence of 4,422 extrasolar planets in 3,280 star systems, with an additional 7,445 candidates awaiting confirmation.

Naturally, this raises some questions. If there is intelligent life out there that has similar capabilities to our own – and the same burning sense of curiosity – could it be watching us too? Equally important is the question of how many of be able to detect us. According to new research conducted by a team from Cornell and the American Museum of Natural History, there are 2,034 star systems within 326 light-years of Earth that would be watching us right now!

There’s a Problem With Hubble, and NASA Hasn’t Been Able to fix it yet

The Hubble Space Telescope could be considered the first of the Super Telescopes. In this image it is being released from the carbo bay of the Space Shuttle Discovery in 1990.

For over thirty years, the Hubble Space Telescope has been in continuous operation in Low Earth Orbit (LEO) and revealing never-before-seen aspects of the Universe. In addition to capturing breathtaking images of our Solar System and discovering extrasolar planets, Hubble also probed the deepest reaches of time and space, causing astrophysicists to revise many of their previously-held theories about the cosmos.

Unfortunately, Hubble may finally be reaching the end of its lifespan. In recent weeks, NASA identified a problem with the telescope’s payload computer which suddenly stopped working. This caused Hubble and all of its scientific instruments to go into safe mode and shut down. After many days of tests and checks, technicians at the NASA Goddard Space Flight Center have yet to identify the root of the problem and get Hubble back online.

Could Life Exist in the Atmosphere of a sub-Neptune Planet?

Earth is perfectly suited for organic life. It stands to reason then that similar worlds orbiting distant stars might also be rich with life. But proving it will be a challenge. One of the better ways to discover extraterrestrial life will be to study the atmospheres of inhabited exoplanets, but Earth is fairly small for a planet and has a thin atmosphere compared to larger worlds. It will be much easier to study the atmospheres of gas planets, but could such worlds harbor life? A new paper in Universe argues it could.

A Newly-Discovered (Almost) Dwarf Planet Will Come Surprisingly Close in 2031

It’s good to remember how little we know about the outer solar system. Humans only really began observing it within the past 100 years, and given the constraints on that observations there are still plenty of things we don’t know about. For example, researchers recently found an object almost the size of a dwarf planet that is inbound to the inner solar system, with an estimated orbital period of over 2 million years, more than six the lifetime of the modern human species.

This is why Martian Colonists are Going to Wish They had an Atmosphere Above Them

There will be all sorts of risks for any future colonists on Mars, such as extreme weather and temperatures, radiation, and the human physiological problems associated with living in with decreased gravity. But another issue means colonists on Mars will have to be on a constant lookout above their heads.

Space Perspective Puts Tickets for Stratospheric Balloon Tours on Sale

Florida-based Space Perspective is opening its ticket window for 20-mile-high balloon flights that provide an astronaut’s-eye view of Earth.

The list price for a six-hour trip up into the stratosphere and back is $125,000. Flights are scheduled to begin as soon as late 2024.

Space Perspective’s co-CEOs, Taber MacCallum and Jane Poynter, unveiled the outlines of their plan for trips in a balloon-borne capsule called Spaceship Neptune a year ago. Since then, the concept has matured. Just last week, the company announced that it conducted a successful uncrewed test of its Neptune One prototype over Florida.

The trial balloon lifted off from the Space Coast Spaceport, located next to NASA’s Kennedy Space Center, and rose to a height of 108,409 feet during a 6-hour, 39-minute flight. An onboard camera captured spectacular views of Earth below the black sky of space.

Betelgeuse's Mysterious Dimming Solved. It was… Dust

At the beginning of 2020, the red giant star Betelgeuse started to dim significantly. Betelgeuse has been known to vary in brightness, but this one was unusual. It grew much dimmer than usual, and for a longer period. Since Betelgeuse is a star at the end of its life, it led some to speculate that perhaps it would go supernova. Astronomers didn’t think that was likely, and of course, Betelgeuse didn’t explode, and gradually its usual brightness returned. But astronomers were puzzled as to why Betelgeuse grew so dim.
