At this point, SpaceX could claim to be both a rocket company and also a maritime shipping company.  The company owns a fleet of drone ships for the purposes of providing their rockets with a safe place to retrograde land in the ocean without having to splash down. In the past, they actually had additional ships for fairing catching, Dragon Capsule recovery, and other support efforts.  But now, the company welcomed its newest drone landing ship with an announcement by Elon Musk on Twitter.  Welcome to the SpaceX: A Shortfall of Gravitas.

We don’t quite understand how the first supermassive black holes formed so quickly in the young universe. So a team of physicists are proposing a radical idea. Instead of forming black holes through the usual death-of-a-massive-start route, instead giant dark matter halos directly collapsed, forming the seeds of the first great black holes.

Sometimes loud explosions are easier to deal with when you know they’re coming.  They are also easier to watch out for.  So when astronomers from the University of Warwick found a rare tear-drop shaped star, known as HD265435, they knew they were looking at a potential new supernova waiting to happen.  The only caveat – it might not actually happen until 70 million years from now.

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.

A team of astronomers has found that giant, organized magnetic fields can help drive some of the most powerful explosions in the universe. But when all is said and done, the shock wave from that blast scrambles any magnetic fields in a matter of minutes.

Space may be pretty, but it’s dangerous. Astronauts face a much higher dose of ionizing radiation than us Earth-bound folks, and a new report says that NASA’s current guidelines and risk assessment methods are in serious need of an update.

Planetary formation theory has been undergoing a lot of changes recently, with an ever expanding litany of events that can potentially impact it.  Everything from gravity to magnetic fields seems to impact this complex process.  Now scientists want to add another confounding factor – massive solar flares thousands of times more powerful than the most powerful we have ever observed from the Sun.

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.

It’s tough to see inside of Saturn, because the atmosphere is opaque to all wavelengths of radiation. We have to rely on computer simulations and physics-based guesswork to try to understand the interior of that giant world. But researchers are becoming more adept at a different technique: looking for the slightest motions in the rings of Saturn.

If it were’t for an enormous halo of dark matter enveloping our galaxy, the spin-rate of our central bar should stay pretty constant. But researchers have recently inferred that it has slowed down by almost 25% since its formation, a clear sign of the presence of dark matter.

Planets move in mysterious ways.  Or at least their surfaces do.  Earth famously has a system of tectonic plates that drives the movement of its crust.  Those plate tectonics are ultimately driven by the flow of material in the mantle – the layer directly below the crust.  Now, scientists have found a slightly different deformation mechanic on our nearest sister planet – Venus.

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).

Magnetic fields are great for lots of things – directing explorers, levitating trains, and containing nuclear fusion reactions are just an example of what these invisible forces can do.  Now we can ascribe another feature to magnetic fields – they can give planets a rocky core.

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.

Predicting volcanic eruptions is notoriously tricky. In large part this is because volcanos are unique, each with their own quirks and personalities: the lessons learned from studying one volcano may not apply directly to another. Luckily, researchers are getting better at finding warning signs that they can apply broadly. Some of the most well-known are heightened seismic activity, rising temperatures, expanding magma pools, and the release of gases. New research using satellite imagery now offers a new warning sign for underwater volcanos: a change in the color of the ocean.

These days it seems you can’t walk through a bookstore without bumping into a book or magazine pointing out the negative consequences of climate change.  Everything from the hottest years on record to ruining astronomy can be tied to climate change.  Now some new science lays another potential problem at climate change’s feet – the Earth is retaining more than twice as much heat annually as it was 15 years ago.

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.

Surprising findings sometimes come in small packages.  And sometimes those small packages have to be delivered by very big systems.  Physicists at MIT made some surprising findings from a very small radioactive molecule that was created in an accelerator at CERN.  They believe that, if studied closely enough, these new types of radioactive molecules could shine some light on why there is more matter than anti-matter in the universe.

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 20th. 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).

Spacewalks are a relatively rare occurrence, and they normally draw at least a moderate amount of media coverage.  So when a team of Chinese astronauts performed a spacewalk outside of their newly launched space station for the first time, it was bound to attract some notice.  The successful walk installed equipment, including cameras, outside of the new Tiangong (“Heavenly Palace”) station.

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.
