Shanghai is About to Open the World’s Largest Astronomy Museum

China has certainly been making its growing power and influence felt in recent years, especially when it comes to the realm of space exploration and science. In the past ten years alone, China has deployed the three space stations with their Tiangong (“Heavenly Palace”) program, unveiled the Long March 5 heavy launch rocket, and sent robotic missions to the far side of the Moon and the surface of Mars.

Here on Earth, facilities like the Five hundred meter Aperture Space Telescope (FAST) illustrate China’s growing accomplishments in space and astronomy. And on Friday (July 16^th), the largest museum in the world dedicated to the study of space – the Shanghai Astronomy Museum – will open its doors. The purpose and design of this museum is to highlight China’s accomplishments in space and astronomy, as well as the country’s future ambitions in space.

According to Elon, Starship Could Chomp up Space Junk

At their South Texas Launch Facility, just outside of the village of Boca Chica, SpaceX is gearing up to test the Super Heavy, the booster element of their Starship launch system. This massive reusable first stage rocket will be responsible for sending the Starship orbital vehicle to space, where it will deliver satellites to orbit, payloads and people to the Moon, and (if all goes as planned) the first human settlers to Mars.

According to a recent statement issued by SpaceX founder Musk Musk, the Starship could also be used to “chomp up debris” in Earth orbit. As usual, the statement was issued via Twitter, where Musk was once again addressing questions posted by followers and fans. The topic arose after Musk shared the latest updates about Starlink, one of a handful of satellite constellations that are bringing broadband internet services to every corner of the planet.

A Nearby White Dwarf Might be About to Collapse Into a Neutron Star

About 97% of all stars in our Universe are destined to end their lives as white dwarf stars, which represents the final stage in their evolution. Like neutron stars, white dwarfs form after stars have exhausted their nuclear fuel and undergo gravitational collapse, shedding their outer layers to become super-compact stellar remnants. This will be the fate of our Sun billions of years from now, which will swell up to become a red giant before losing its outer layers.

Unlike neutron stars, which result from more massive stars, white dwarfs were once about eight times the mass of our Sun or lighter. For scientists, the density and gravitational force of these objects is an opportunity to study the laws of physics under some of the most extreme conditions imaginable. According to new research led by researchers from Caltech, one such object has been found that is both the smallest and most massive white dwarf ever seen.

Richard Branson and Friends Reach the Edge of Space, and Lived to Tell About it!

Early this morning, Sir Richard Branson and Virgin Galactic achieved a major milestone in the development of commercial space travel. Along with a team of specialists, Branson traveled to the edge of space aboard the VSS Unity and made it safely back to Earth. In so doing, Branson and his company have also fired the latest salvo in the ongoing race between the titans of the commercial space industry (aka. NewSpace).

Richard Branson will fly on SpaceShipTwo this weekend. Welcome to the New (Edge of) Space Race!

It’s no secret that the commercial space industry (aka. NewSpace) has become immensely lucrative in recent years, nor the fact that it has become intensely competitive as a result. To illustrate, one needs to look no further than the top three NewSpace companies in the world right now: SpaceX, Blue Origin, and Virgin Galactic. Between these three companies, all founded by billionaires with similar visions, a new space race has begun.

In recent months, the race has intensified as Jeff Bezos announced that he would be going to space on the inaugural flight of the New Shepard rocket. In response, Virgin Galactic founder and CEO Richard Branson announced earlier this week that he would fly aboard the VSS Unity as it makes its latest test flight. If successful, this mission – scheduled for Sunday, July 11^th (weather permitting) – will see Branson become the first billionaire to go to space.

After British Columbia’s Record-Breaking Heatwave, Here Come the Wildfires

Every day, there are more indications that show how anthropogenic factors are causing uncomfortable changes in our climate. Here in beautiful British Columbia, this means that wildfires are once again threatening countless acres of forests, communities, and wildlife. By the end of June 2021, more than 40 wildfires were raging across the province, including a rather substantial cluster around the town of Lytton.

Located just 150 km (about 93 mi) northeast of the city of Vancouver, Lytton, had to be evacuated on June 30th after an extreme heatwave led to wildfire sweeping through the area. These wildfires and the impact they were having at the time was being monitored by some of NASA’s Earth Observatory satellites. In a series of images recently shared on their website, they show the fires that were raging near Lytton just hours before the evacuation.

Wally Funk From the Mercury 13 Will be Joining Jeff Bezos on his Flight to the Edge of Space

This month, two billionaires will be flying to space aboard their very own commercial launch vehicles. The first to go will be Amazon founder Jeff Bezos, who will be a passenger aboard the inaugural crewed flight of the New Shepard on July 20^th. Mark Bezos, Jeff’s brother, will be accompanying him on this flight, as will the person who won the auction that wrapped up on June 12th (they bid $28 million for the seat).

On July 1st, Blue Origin announced that the fourth passenger on this historic flight would be Wally Funk, a pioneer in aerospace who trained to become an astronaut back in the 1960s. As part of the “Mercury 13” Woman in Space Program, Funk was one of several qualified test pilots and graduated at the top of her class. And now, sixty years later, she is once again a pioneer since she is the oldest person that has ever flown to space.

There are Probably Many More Earth-Sized Worlds Than Previously Believed

This illustration depicts a planet partially hidden in the glare of its host star and a nearby companion star. After examining a number of binary stars, astronomers have concluded that Earth-sized planets in many two-star systems might be going unnoticed by transit searches, which look for changes in the light from a star when a planet passes in front of it. The light from the second star makes it more difficult to detect the changes in the host star’s light when the planet passes in front of it.

In the past decade, the discovery of extrasolar planets has accelerated immensely. To date, 4,424 exoplanets have been confirmed in 3,280 star systems, with another 7,453 awaiting confirmation. So far, most of these planets have been gas giants, with about 66% being similar to Jupiter or Neptune, while another 30% have been giant rocky planets (aka. “Super-Earths). Only a small fraction of confirmed exoplanets (less than 4%) have been similar in size to Earth.

However, according to new research by astronomers working at NASA Ames Research Center, it is possible that Earth-sized exoplanets are more common than previously thought. As they indicated in a recent study, there could be twice as many rocky exoplanets in binary systems that are obscured by the glare of their parent stars. These findings could have drastic implications in the search for potentially habitable worlds since roughly half of all stars are binary systems.

Tales of a ‘Drunken Comet’- Astronomers Detect Alcohol Leaking From 46P/Wirtanen into Space

A close pass of Comet Wirtanen in 2018 offered researchers an unprecedented opportunity.

Comets are full of surprises. Not only do they often under- or very occasionally over- perform versus expectations, but they also offer a glimpse of the remnants of the very early solar system. In December 2018, astronomers had an unprecedented opportunity to study one of these relics of the early solar system up close as Comet 46P/Wirtanen sped by Earth just 30 times the Earth-Moon distance (7.1 million miles away) on its closest passage for this century.

After Just 6 Weeks of Construction, Super Heavy is Built and Ready to Move

As usual, the SpaceX South Texas Launch Facility, located near the village of Boca Chica, is the focal point of a lot of attention. Almost two months ago, crews at the facility began working on the first true Super Heavy prototype, the launch stage of SpaceX’s Starship. After six weeks of assembly, SpaceX rolled the Super Heavy Booster 3 (B3) out of the “High Bay” (where it was assembled) and installed it onto the launch pad.
