The Tarantula Nebula is a star formation region in the Large Magellanic Cloud (LMC). Tarantula is about 160,000 light-years away and is highly luminous for a non-stellar object. It’s the brightest and largest star formation region in the entire Local Group of galaxies.
But it shouldn’t be.

United Launch Alliance (ULA) is the oldest commercial space company in the U.S., with over 150 consecutive launches to its credit. For almost two decades, the company has been providing launch services using the expendable Delta II, Delta IV, and Atlas V rockets. Faced with growing competition and political pressure, ULA began working on a new heavy-launch vehicle, the Vulcan rocket, in 2014. Once realized, this rocket will allow the ULA to remain competitive in the burgeoning NewSpace market and meet the needs of the National Security Space Launch (NSSL).
On June 7th, the first stage of the Vulcan successfully test-fired its two Blue Origin BE-4 engines at Space Launch Complex 41 (SLC-41) at the Cape Canaveral Space Force Station (CCSFS) in Florida. The success of this test, designated Certification-1 (Cert-1), places the ULA on track to launch test its next-generation heavy-launch vehicle. Once realized, the Vulcan rocket will provide services ranging from the deployment of small satellites and payloads to reusable crewed spacecraft, like Boeing’s CST-100 Starliner space capsule and Sierra Nevada’s Dream Chaser spaceplane.

Technology Readiness Levels (or TRLs) are commonly used in the space industry to determine what level of development a technology has undergone. For space technologies, eventually, they get to a TRL where they have to be used in space. In some cases, that can be difficult, as getting a ride on a launch is both risky and expensive. So it’s good news for Oxford Space Systems (OSS) that they penned an agreement with Surrey Satellites Technology Ltd (SSTL) to prove one of their new technologies on an actual flight.

Until recently, there were only ten known stars on trajectories that will allow them to escape the Milky Way Galaxy, thrown astray by powerful supernova explosions. A new study using data from ESA’s Gaia survey this June has revealed an additional six runaways, two of which break the record for the fastest radial velocity of any runaway star ever seen: 1694 km/s and 2285 km/s.

He’s done it again, outdoing even his own incredible work.
Over the years, we’ve written many articles to share the beautiful and mind-bending astrophotography of Thierry Legault. Each year he seems to come up with ideas to try to surpass even his own craziest attempts of astrophotography feats – such as capturing spy satellites in orbit, or snapping pictures of the International Space Station (ISS) transiting the Sun during a solar eclipse.
Now, he was able to take pictures of the ISS transiting the Sun while two astronauts were doing a spacewalk. As an added challenge, Legault made sure he was in the right place at the right time so he could capture the ISS (and astronauts) while they were passing by three enormous sunspots.
WHAT??

There are always more space missions than there is money to support them. Ultimately, some make the funding cut, and some do not. Various factors go into that decision, though those factors can change over the years and decades that some of these missions are designed to take. But the more ideas, the better, and now a new idea has sprung up from a group of scientists at SWRI, NASA, and the University of Minnesota, among others. It involves four different probes sent to various points in the solar system to observe the Sun as it has never been seen before – and just in time to see its most spectacular display in 2032.

Researchers have discovered an exciting new source of gravitational waves. They are the remnants left over from a supernova explosion, and they may just reveal the secrets to how those explosions work.

Despite the enormous densities, the early universe didn’t collapse into a black hole because, simply put, there was nothing to collapse into.

Space agencies will play a vital role in the developing space economy, especially in the beginning. But what will the part of the biggest of all space agencies be when considering how space resources, especially those on the Moon, are accessed? NASA has a plan for that as it does for so many other things – and this article will dig into a slideshow that describes that plan in detail.

Where does the solar wind come from? That’s a question solar physicists have wanted an answer to for decades. Now, the Parker Solar Probe is showing them exactly where this stream of particles exits our star on a journey out through interplanetary space.
