There are likely millions of “rogue” or free-floating planets (FFPs) spread through the galaxy. These planets, which aren’t big enough to become stars but also aren’t beholden to a star’s gravity, are some of the hardest objects for astronomers to spot, as they don’t give off their own light, and can only be seen when they cross in front of something that does give off its own light. Enter Euclid, a space telescope that launched last year. Its primary mission is to observe the universe’s history, but a new paper describes an exciting side project – finding FFPs in Orion.

It should not be surprising that Venus is dry. It is famous for its hellish conditions, with dense sulphurous clouds, rains of acid, atmospheric pressures comparable to a 900 meter deep lake, and a surface temperature high enough to melt lead. But it’s lack of water is not just a lack of rain and oceans: there’s no ice or water vapour either. Like Earth, Venus is found within our Solar System’s goldilocks zone, so it would have had plenty of water when it was first formed. So where did all of Venus’s water go?

I’ve seen some pretty incredible things using my eyes.. First off of course, is the stunning sight of a dark star filled sky, then there is the incredible sight of the Andromeda Galaxy 2.5 million light years away. Planets too can of course be seen as they slowly move across the sky but it’s a little more unusual to see something that reminds us the Universe changes. Well, we have an opportunity  in just a few weeks time. The star T Corona Borealis (T CrB) will brighten about 1,500 times so it can be seen with the unaided eye. Miss it though and you will have to wait another 80 years!

We live in a Universe studded with black holes. Countless stellar mass and supermassive ones exist in our galaxy and most others. It’s likely they existed as so-called “primordial” black holes in the earliest epochs of cosmic history. Yet, there seems to be a missing link category: intermediate-mass black holes (IMBH). Astronomers have searched for these rare beasts for years and there’s only one possible observation thanks to gravitational-wave data. So, where are they?

Through the Artemis Program, NASA will send astronauts to the lunar surface for the first time since 1972. While the challenges remain the same, the equipment has evolved, including the rocket, spacecraft, human landing system (HLS), and space suits. In preparation for Artemis III (planned for September 2026), NASA recently conducted a test where astronauts donned the new space suits developed by Axiom Space and practiced interacting with the hardware that will take them to the Moon.

Red dwarf stars, also known as M-dwarfs, dominate the Milky Way’s stellar population. They can last for 100 billion years or longer. Since these long-lived stars make up the bulk of the stars in our galaxy, it stands to reason that they host the most planets.

Despite being extraordinarily difficult to detect for the first time, gravitational waves can be found using plenty of different techniques. The now-famous first detection at LIGO in 2015 was just one of the various ways scientists had been looking. A new paper from researchers from Europe and the US proposes how scientists might be able to detect some more by tracking the exact position of the upcoming Uranus Orbiter and Probe (UOP).

SpaceX’s Starship earned high marks today in its fourth uncrewed flight test, making significant progress in the development of a launch system that’s tasked with putting NASA astronauts on the moon by as early as 2026.

Thirty-four years is a long time for a telescope. Yet, that is how long the veteran workhorse of NASA’s space telescope fleet has been operating. Admittedly, Hubble was served by several repair missions during the space shuttle era. Still, the system has been floating in the void and taking some of humanity’s most breathtaking pictures ever captured since April 24th, 1990. But now, time seems to be finally catching up with it, as NASA plans to limit some of its operations to ensure its continued life, starting with gyroscopes. 

A pair of Chinese taikonauts have completed an eight-hour spacewalk repairing damage to the Tiangong Chinese Space Station’s solar panels. It’s believed the damage was caused by tiny pieces of space debris, which impacted the solar wings and degraded their function. They performed a first repair spacewalk in December 2023 and completed the repairs with their second trip outside in March 2024. The Shenzhou 17 crew were the sixth group living in Tiangong and were relieved by the Shenzhou-18 team in late April.

After many delays and two scrubbed launch attempts, Boeing’s CST-100 Starliner successfully launched earlier today! The Crewed Flight Test (CFT) took off from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida, at 10:52 a.m. EDT (07:52 PDT) atop a ULA Atlas V rocket. For this mission, the capsule is carrying two NASA astronauts: Barry “Butch” Wilmore (commander) and Sunita “Suni” Williams (pilot). They are expected to reach the International Space Station (ISS) at 12:15 p.m. EDT (09:15 a.m. PDT) on Thursday, June 6th.

The European Space Agency has retired its Ariane 5 rocket, and all eyes are on its next generation, Ariane 6. The rocket’s pieces have been arriving at the Kourou facility in French Guiana and are now assembled.  ESA has now announced they’ll attempt a test launch on July 9th and hope to complete a second flight before the end of 2024. This new heavy-life rocket has a re-ignitable upper stage, allowing it to launch multiple payloads into different orbits.

I have always wanted a 3D printer but never quite found a good enough reason to get one. Seeing that NASA are now 3D printing metal is even more tantalising than a plastic 3D printer. However, thinking about it, surely it is just a computer controlled soldering iron! I’m sure it’s far more advanced than that! Turns out that the first print really wasn’t much to right home about, just an s-curve deposited onto a metal plate! It does however prove and demonstrate the principle that a laser can liquify stainless steel and then deposit it precisely in a weightless environment. 

What is Dark Matter? That question is prominent in discussions about the nature of the Universe. There are many proposed explanations for dark matter, both within the Standard Model and outside of it.

NASA are planning on building a telescope to hunt for habitable worlds. The imaginatively named ‘Habitable Worlds Observatory’ is at least a decade away but NASA have started to develop the underlying technology needed. The contracts have been awarded to three companies to research the next-generation optics, mission designs and telescope features at a cost of $17.5 million. Work should begin late summer 2024.

When the James Webb Space Telescope was launched at the end of 2021, we expected stunning images and illuminating scientific results. So far, the powerful space telescope has lived up to our expectations. The JWST has shown us things about the early Universe we never anticipated.

On January 19th, 2024, the Japanese Aerospace Exploration Agency (JAXA) successfully landed its Smart Lander for Investigating Moon (SLIM) on the lunar surface. In so doing, JAXA became the fifth national space agency to achieve a soft landing on the Moon – after NASA, the Soviet space program (Interkosmos), the European Space Agency, and the China National Space Agency (CNSA). SLIM has since experienced some technical difficulties, which included upending shortly after landing, and had to be temporarily shut down after experiencing power problems when its first lunar night began.

For a small, lumpy chunk of rock that barely reflects any light, Mars’ Moon Phobos draws a lot of attention. Maybe because it’s one of only two moons to orbit the planet, and its origins are unclear. But some of the attention is probably because we have such great images of it.

There are plenty of problems that spacecraft designers have to consider. Getting smacked in the sensitive parts by a rock is just one of them, but it is a very important one. A micrometeoroid hitting the wrong part of the spacecraft could jeopardize an entire mission, and the years of work it took to get to the point where the mission was actually in space in the first place. But even if the engineers who design spacecraft know about this risk, how is it best to avoid them? A new programming library from research at NASA could help.

The Standard Model of particle physics does a good job of explaining the interactions between matter’s basic building blocks. But it’s not perfect. It struggles to explain dark matter. Dark matter makes up most of the matter in the Universe, yet we don’t know what it is.

Our Moon is shrinking and has been doing so since just after its formation ~4.5 billion years ago from a collision with the young Earth. That shrinkage, along with a constant rain of micrometeorites, causes lunar seismic activity. NASA plans to send two instruments to the Moon to measure its moonquakes. Those dual seismometers share technology first used on Mars by the InSight lander to measure more than a thousand marsquakes.
