More than 4.5 billion years ago, a huge world, potentially as large as the moon or even Mars, traveled around the young Sun before a violent collision shattered it into pieces. Scientists now say they have found the first direct evidence that this long-lost planetary embryo, known as a protoplanet, once existed. The discovery, described…
NASA’s Chandra X-ray Observatory has released four stunning images of cosmic wonders, depicted in red, white and blue to coincide with the United States’ 250th anniversary on July 4. The four images reveal superheated gas in a distant galaxy cluster, the swirling spiral galaxy known as Messier 94, a glowing nebula found in our own…
Back to Article List Today in the history of astronomy, Cassini arrives after a seven-year journey. Were they moons? Ears? Handles? Galileo couldn’t parse the rings of Saturn (seen in this Cassini-Huygens image from 2004). Credt: NASA/JPL/Space Science Institute On July 1, 2004, the Cassini-Huygens mission, a collaborative undertaking by NASA, the European Space Agency…
In an arid world of ice and snow, a glacier is ‘bleeding’. A deep red flow of water stains the white landscape surrounding it, remaining liquid even at temperatures well below freezing. And it’s been doing this for more than a century. This is Antarctica’s Blood Falls – and its internal world is even stranger…
Imagine a muscle as something that has spent your entire life in conversation with gravity, constantly sensing your body’s weight, constantly adjusting, constantly being told it is needed. Now imagine cutting that conversation off entirely. That is in some ways what happens to an astronaut’s body in orbit, and it is the problem at the…
A patch of water south of Greenland and Iceland has cooled by nearly 1.8 degrees Fahrenheit since 1900. A new study suggests that it shows a crucial system of ocean currents is weakening, which could alter Earth’s climate Michele Debczak | Correspondent June 30, 2026 12:17 p.m. The “cold blob,” shown in blue near the…
A restless Earth-facing sunspot unleashed a powerful X-class solar flare on June 30, triggering radio blackouts across parts of North America. The X1.1 solar flare erupted from sunspot region AR4479, peaking at 4:50 p.m. EDT (2050 GMT) according to NOAA’s Space Weather Prediction Center. The intense burst of X-rays released during the eruption reached Earth…

The universe is ready for its close-up! That’s because today marks the day that the Vera C. Rubin Observatory begins it’s 10-year mission to shoot the greatest cosmic move ever created. The decade-long project officially known as the Legacy Survey of Space and Time (LSST) is set to revolutionize our view of the universe. That…
Millions of stars. Thousands of hidden worlds. One unprecedented view of our galaxy. Three years since launch, ESA’s Euclid space telescope reveals the Milky Way galaxy’s centre in extraordinary detail: a mosaic of tens of millions of stars captured in just 26 hours.But this is more than an image. It is a map of stellar…
