One of the greatest benefits to come from space telescopes and ground-based observatories that take advantage of advanced imaging techniques is their ability to see farther into space (and hence, further back in time). In so doing, they are revealing things about the earliest galaxies, which allows astronomers to refine theories of how the cosmos formed and evolved.
For example, new research conducted by the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has found a “ring galaxy” that existed 11 billion years ago (about 3 billion years after the Big Bang). This extremely rare structure, which the team describes as a “cosmic ring of fire,” is likely to shake up cosmological theories of how the cosmos has changed over time.

Today, on Saturday, May 30th, NASA and SpaceX successfully launched the Crew Dragon to space with two astronauts for the first time. Far from just a demonstration, this launch signaled the restoration of domestic launch capability to US soil! From this day forward, NASA astronauts will no longer be dependent on foreign launch providers (like Roscosmos) to send astronauts to the International Space Station (ISS).

Oh Planet Nine, when will you stop toying with us?
Whether you call it Planet Nine, Planet X, the Perturber, Jehoshaphat, “Phattie,” or any of the other proposed names—either serious or flippant—this scientific back and forth over its existence is getting exhausting.
Is this what it was like when they were arguing whether Earth is flat or round?

Earlier today (Friday, May 29th), at 01:49 p.m. local time (02:49 p.m. EDT; 11:49 PDT), SpaceX Starship prototype (SN4) exploded on the company’s test pad near Boca Chica, Texas. The explosion occurred two minutes after ground crews commenced a static fire test of its Raptor engine. This test was intended to test the Raptor and the Starship design once more in preparation for a major milestone – a 150 m (500 ft) hop test – this summer.

On Wednesday, May 27th, NASA and SpaceX geared up for what was sure to be a historic event! After years of hard work, the Crew Dragon capsule developed through NASA’s Commercial Crew Program would dock with the ISS for the first time. This launch would effectively restore domestic-launch capability to the United States, something it lost in 2011 with the retiring of the Space Shuttle. Unfortunately, the weather didn’t get the memo!
Less than 15 minutes before the Crew Dragon was to launch atop a Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida, mission controllers scrubbed the flight because the weather was not clearing up. As a result, NASA and SpaceX pushed the launch of the Crew Dragon to their two backup launch opportunities, both of which will be happening this weekend.

Even though Earthling scientists are studying Mars intently, it’s still a mysterious place.
One of the striking things about Mars is all of the evidence, clearly visible on its surface, that it harbored liquid water. Now, all that water is gone, and in fact, liquid water couldn’t survive on the surface of the Red Planet. Not as the planet is now, anyway.
But it could harbour water in the past. What happened?

For the child inside all of us space-enthusiasts, there might be nothing better than discovering a new type of explosion. (Except maybe bigger rockets.) And it looks like that’s what’s happened. Three objects discovered separately—one in 2016 and two in 2018—add up to a new type of supernova that astronomers are calling Fast Blue Optical Transients (FBOT).

If we ever intend to send crewed missions to deep-space locations, then we need to come up with solutions for how to keep the crews supplied. For astronauts aboard the International Space Station (ISS), who regularly receive resupply missions from Earth, this is not an issue. But for missions traveling to destinations like Mars and beyond, self-sufficiency is the name of the game!
This is the idea behind projects like BIOWYSE and TIME SCALE, which are being developed by the Centre for Interdisciplinary Research in Space (CIRiS) in Norway. These two systems are all about providing astronauts with a sustainable and renewable supply of drinking water and plant food. In so doing, they address two of the most important needs of humans performing long-duration missions that will take them far from home.

The closest star to the Sun is a small red dwarf star known as Proxima Centauri. It is only 4.2 light-years away and is now known to have an Earth-sized planet in its habitable zone. That doesn’t mean there is life orbiting the nearest star, but its proximity should help us understand the possibilities.

One of the most striking features on Earth are the curious flows of lava as it cools, forming undulating ropes of rock known by the Hawaiian word pahoehoe. New research simulating conditions on Mars now reveals that the red planet has its own kind of pahoehoe…but made of mud.
