Dark matter makes up roughly 85 percent of all the matter in the universe. We have never directly detected a single particle of it. But a new method developed by physicists at MIT and across Europe may have just opened a door we didn't know existed. When two black holes collide and merge, they send ripples through the fabric of spacetime, these are known as gravitational waves and if those black holes happened to spiral through a dense cloud of dark matter on their way in, those waves carry an imprint of it. For the first time, scientists have a technique to read that imprint and one signal in the existing data is already raising eyebrows.

Artemis II has barely left the headlines. On April 1st 2026, four astronauts climbed aboard NASA's Orion spacecraft, rode the most powerful rocket ever to carry humans beyond low Earth orbit, and swung around the far side of the Moon. The world watched. Now, before the dust has settled, NASA has outlined its plans for what comes next. Artemis III won't be landing on the Moon. But what it will do is arguably just as important and if history is any guide, it's exactly the kind of mission that makes the difference between a Moon landing and a disaster.

Right now, as you read this, Earth is drifting through a cloud of debris from an ancient stellar explosion. Stardust, real stardust, is raining down on us so thinly scattered that we have only just found the proof. Locked inside Antarctic ice cores up to 80,000 years old, an international team led by the Helmholtz-Zentrum Dresden-Rossendorf has discovered traces of iron-60, a radioactive isotope that can only be created in the heart of an exploding star.

A planetary odd couple — a mini-Neptune and a hot Jupiter — probably formed much farther away from their star before migrating closer in.

The nation’s top court extended a stay on a lower court order banning telemedicine access to mifepristone, a drug used in medication abortions—but the order sets up a longer legal fight

For ten years, astronomers at UCLA have been pointing one of the world's most powerful radio telescopes at the stars and listening. Not for pulsars or gas clouds, or the hiss of the cosmic microwave background, but for something far more extraordinary. A signal from another civilisation. The result of a decade's work, 70,000 stars, and 100 million candidate signals is now in and every single one of them was us! But far from being a disappointment, the findings are among the most rigorous and revealing in the history of the search for extraterrestrial intelligence.

On Thursday, NASA issued a Request for Proposal (RFP), seeking industry collaboration for the Mars Telecommunications Network.

Reliable, high bandwidth communications is necessary to relay science data, high-definition imagery, and critical information during Mars missions. The network will use high-performance Mars telecommunications orbiters at the Red Planet to support future surface, orbital, and human exploration.

This RFP builds on a draft released April 2, as well as insights gathered during the accompanying industry day at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where commercial partners provided feedback on agency objectives for the Mars Telecommunications Network.

The request seeks responses that address both current and future operational missions. It also seeks a science payload accommodation that will be selected by NASA’s Science Mission Directorate. Industry is asked to respond within 30 calendar days of the posting, and the network should be ready to operate at Mars no later than 2030.

The Mars Telecommunications Network is part of NASA’s evolving space architecture, extending continuous network services beyond Earth to the Moon and Mars. The Mars Telecommunications Network is part of NASA’s SCaN (Space Communications and Navigation) Program’s Moon to Mars strategy, and is enabled by the direction and funding provided by Congress in the Working Families Tax Cut Act.

One of the core community surveys of NASA’s Nancy Grace Roman Space Telescope, the Galactic Bulge Time-Domain Survey, is expected to locate over a thousand exoplanets that orbit far away from their stars, beyond the orbital distance of Earth from the Sun. Although Roman hasn’t launched yet, astronomers already are gathering useful supporting data by utilizing NASA's Hubble Space Telescope, which could assist astronomers in analyzing Roman data.

Preparations for Next Moonwalk Simulations Underway (and Underwater)

NASA is collaborating with Eta Space of Rockledge, Florida, on an in‑orbit technology demonstration to advance a key capability for future deep space missions. The Liquid Oxygen Flight Demonstration, or LOXSAT, will test cryogenic fluid management technologies necessary for creating in-space propellant depots, essentially gas stations in space, that could support long-term exploration.

The LOXSAT payload is displayed inside Rocket Lab’s Spacecraft Production Complex in Long Beach, California. Rocket Lab

During a nine-month mission, LOXSAT will demonstrate 11 cryogenic fluid management technologies. Eta Space built LOXSAT as part of a NASA Tipping Point opportunity, and Rocket Lab is providing spacecraft and launch services to deliver it to low Earth orbit. The LOXSAT payload has been integrated with a Rocket Lab Photon satellite bus and will launch aboard the company’s Electron rocket from Launch Complex 1 on New Zealand’s Mahia Peninsula no earlier than July 17.

The technologies that LOXSAT will demonstrate were selected to address the core challenges of using cryogenic, or super-cold, propellants in microgravity, including reducing boiloff, transferring propellant, maintaining tank pressure, and gauging propellant levels. Data collected from these tests will support development of future in-space propellant depots that could refuel spacecraft as they journey to the Moon, Mars, or other deep space destinations.

NASA’s LOXSAT team is composed of members of the Cryogenic Fluid Management Portfolio Project from NASA’s Marshall Space Flight Center in Huntsville, Alabama, Glenn Research Center in Cleveland, and Kennedy Space Center in Florida. The cryogenic portfolio’s work is part of NASA’s Space Technology Mission Directorate and includes more than 20 individual technology development activities.
