Cosmic Dust Could Have Helped Get Life Going on Earth Life on our planet appeared early in Earth’s history. Surprisingly early, since in its early youth our planet didn’t have much of the chemical ingredients necessary for life to evolve. Since prebiotic chemicals such as sugars and amino acids are known to appear in asteroids and comets, one idea is that Earth was seeded with the building blocks of life by early cometary and asteroid impacts. While this likely played a role, a new study shows that cosmic dust also seeded young Earth, and it may have made all the difference. Although we’ve long knownRead More →

Odysseus Moon Lander Is Tipped Over But Still Sending Data The bad news is that Intuitive Machines’ Odysseus lander is tipped on its side after getting tripped up during its touchdown near the south pole of the moon. The good news? The plucky robotic spacecraft is nevertheless able to send back data. Mission managers at the Houston-based company and at NASA, which is paying $118 million to support Odysseus’ space odyssey, are working on ways to maximize the scientific payback over the next nine or 10 days. “The vehicle is stable, near or at our intended landing site,” Intuitive Machines CEO Steve Altemus said todayRead More →

Finally! Webb Finds a Neutron Star from Supernova 1987A I can remember seeing images of SN1987A as it developed back in 1987. It was the explosion of a star, a supernova in the Large Magellanic Cloud. Over the decades that followed, it was closely monitored in particular the expanding debris cloud. Predictions suggested there may be a neutron star or even a black hole at the core but the resolution of the telescopes was insufficient to pick anything up. Now we have the James Webb Space Telescope and using its more powerful technology, signs of a neutron star have been detected.  Supernova are among theRead More →

A Capsule With Antiviral Drugs Grown in Space Returns to Earth On Wednesday, February 21st, at 01:40 p.m. PST (04:40 p.m. EST), an interesting package returned to Earth from space. This was the capsule from the W-1 mission, an orbital platform manufactured by California-based Varda Space Industries, which landed at the Utah Test and Training Range (UTTR). Even more interesting was the payload, which consisted of antiviral drugs grown in the microgravity environment of Low Earth Orbit (LEO). The mission is part of the company’s goal to develop the infrastructure to make LEO more accessible to commercial industries. Founded in 2020 by former SpaceX employeesRead More →

The Sun Gets Feisty, Throwing Off Three X-Class Flares Within 24 Hours The Sun is heading toward solar maximum (which is likely to be about a year away) and as it does, there will be more sunspots, solar flares and coronal mass ejections. Over the last 24 hours there has been three, yes three X-class flares, the first peaking at X1.9, the second 1.7 and the final one a mighty 6.3. Flares of this magnitude caused radio blackouts, disruption to mobile phones and radio transmissions.   The solar cycle is an 11 year recurring pattern of activity that is driven by the Sun’s magnetic field.Read More →

A Star Passed Through the Oort Cloud Less Than 500,000 Years Ago. It Wasn’t the Only One. As stars in the Milky Way move through space, some of them have an unexpected effect on the Solar System. Over time, one comes closer to the Sun during its orbit in the galaxy. Some of them actually get within a light-year of our star and pass through the Oort Cloud. Such close flybys can affect the orbits of the outer planets and send cometary nuclei on a long inward rush to the Sun. Astronomer Igor Yu Potemine at the Université Paul Sabatier in France, and his colleaguesRead More →

A New Space Telescope will Map the Universe and Help Protect the Earth from Asteroids Can we secure our place in the Solar System? Not in any absolute sense because nature can be very unpredictable. But we can make the effort to safeguard our civilization by cataloguing potentially dangerous asteroids. An upcoming space telescope will help. NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) mission will launch no later than April 2025. The orbiting telescope will conduct a two-year all-sky survey in optical and infrared light. The main focus of the mission is to gather data on moreRead More →

Finally! Blue Origin’s New Glenn Goes Vertical on the Launch Pad If you think about space travel and the means of escaping the confines of the Earth then most people, currently, are likely to think about the new Artemis project and the Space Launch System. That’s not the only new development though, Blue Origin have been working on their New Glenn rocket and finally we have got a glimpse of their new offering. The rocket was finally rolled onto the launch pad at Cape Canaveral for testing to commence and we may even see a launch later this year. Blue Origin was founded in 2000Read More →

If Hycean Worlds Really Exist, What are Their Oceans Like? Astronomers have been on the hunt for a new kind of exoplanet in recent years – one especially suited for habitability. They’re called hycean worlds, and they’re characterized by vast liquid water oceans and thick hydrogen-rich atmospheres. The name was coined in 2021 by Cambridge astronomer Nikku Madhusudhan, whose team got a close-up look at one possible hycean world, K2-18b, using the James Webb Space Telescope in 2023. In a newly accepted paper this January, Madhusudhan and coauthor Frances Rigby examined what the internal structure of hycean planets might look like, and what that meansRead More →

Intuitive Machines’ Odysseus Lander Sends Faint Signal From the Moon Intuitive Machines‘ Odysseus lander made space history today — becoming the first commercial spacecraft to survive a descent to the moon, and the first U.S.-built spacecraft to do so since the Apollo 17 mission in 1972. But it wasn’t a trouble-free landing. Ground controllers had a hard time establishing contact with the robotic lander just after the scheduled touchdown time of 6:23 p.m. ET (2323 UTC). Several minutes passed, and then Intuitive Machines mission director Tim Crain reported that there was a faint signal coming from Odysseus’ high-gain antenna. “We’re not dead yet,” he said.Read More →

Intuitive Machines’ Odyssey Lander Sends Faint Signal From the Moon Intuitive Machines‘ Odysseus lander made space history today — becoming the first commercial spacecraft to survive a descent to the moon, and the first U.S. spacecraft to do so since the Apollo 17 mission in 1972. But it wasn’t a smooth landing, and it wasn’t immediately clear what condition the phone booth-sized probe was in. Ground controllers had a hard time establishing contact with the robotic lander just after the scheduled touchdown time of 6:23 p.m. ET (2323 UTC). Several minutes passed, and then Intuitive Machines mission director Tim Crain reported that there was aRead More →

Anti-Satellite Weapons Will Threaten Everyone’s Access to Space It’s a headline straight out of the movies yet the White House has recently confirmed it believes that Russia is building space-based anti-satellite weapon! There seems to be no conclusive evidence what this might be but one option may be a nuclear bomb that would indiscriminately wipe out satellites within a huge volume of space! Not only would it devastate satellites but would cause more problems down on the surface and create a whole load of space junk.  In a statement, the National Security Council spokesperson John Kirby said that he did not believe the weapon hadRead More →

Powerful Jets From a Black Hole are Spawning Star Clusters Supermassive black holes are messy feeders, and when they’re gorging on too much material, they can hurl high-energy jets into the surrounding Universe. Astronomers have found one of the most powerful eruptions ever seen, emanating from a black hole 3.8 billion light-years away. The powerful jets are blowing out cavities in intergalactic space and triggering the formation of a huge chain of star clusters. The black hole is part of a massive galaxy cluster, named SDSS J1531, which contains hundreds of individual galaxies, and all these galaxies have huge reservoirs of hot gas and darkRead More →

We Could Snoop on Extraterrestrial Communications Networks The conditions for life throughout the Universe are so plentiful that it seems reasonable to presume there must be extra-terrestrial civilizations in the galaxy. But if that’s true, where are they? The Search for Extra-terrestrial Intelligence (SETI) program and others have long sought to find signals from these civilizations, but so far there has been nothing conclusive. Part of the challenge is that we don’t know what the nature of an alien signal might be. It’s a bit like finding a needle in a haystack when you don’t know what the needle looks like. Fortunately, any alien civilizationRead More →

Astroscale’s Satellite is Now Chasing Down a Real Piece of Space Debris Space debris is a thing.. It seems whether we explore the Earth or space we leave rubbish in our wake. Thankfully, organisations like Astroscale are trying to combat the problem of debris in space with a new commercial debris inspection demonstration satellite. Named ADRAS-J, the satellite – which is now in orbit – is hunting down an old Japanese upper stage rocket body which was launched in 2009.  It will approach to within 30 metres to study the module from every angle and work out how it can be safely de-orbited by aRead More →
