The summer fire season is well under way in Europe – countries all around the Mediterranean are experiencing record temperatures coupled with huge wildfires that have led to mass evacuations. In this enthralling new ESA documentary, explore how people on the frontline are using space to better monitor and fight the flames.
The exploding comet, known as 12P/Pons–Brooks, is currently approaching its closest point to Earth during its 71-year orbit through the solar system.
The Sturgeon full moon rises on Tuesday, Aug. 1, marking the first of two supermoons in August 2023 and the second supermoon in a series of four across summer.
China has sent 136 kinds of plant seeds to its Tiangong space station for space breeding experiments.
Euclid’s two instruments have captured their first test images. The mesmerising results indicate that the space telescope will achieve the scientific goals that it has been designed for – and possibly much more.

This image shows the irregular galaxy NGC 6822, which was observed by the Near-InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI) mounted on the NASA/ESA/CSA James Webb Space Telescope. As their names suggest, NIRCam and MIRI probe different parts of the electromagnetic spectrum. This allows the instruments to observe different components of the same galaxy, with MIRI especially sensitive to its gas-rich regions (the yellow swirls in this image) and NIRCam suitable for observing its densely packed field of stars.
A collaboration of engineers from NASA and academia recently tested hybrid printed electronic circuits near the edge of space, also known as the Kármán line. The space-readiness test was demonstrated on the Suborbital Technology Experiment Carrier-9, or (SubTEC-9), sounding rocket mission, which was launched from NASA’s Wallops Flight Facility on April 25 and reached an altitude of approximately 174 kilometers (108 miles), which lasted only a few minutes before the rocket descended to the ground via parachute.
In 2026, the European Space Agency (ESA) will launch its next-generation exoplanet-hunting mission, the PLAnetary Transits and Oscillations of stars (PLATO). This mission will scan over 245,000 main-sequence F, G, and K-type (yellow-white, yellow, and orange) stars using the Transit Method to look for possible Earth-like planets orbiting Solar analogs. In keeping with the “low-hanging fruit” approach (aka. follow the water), these planets are considered strong candidates for habitability since they are most likely to have all the conditions that gave rise to life here on Earth.
On a basic level, a star is pretty simple. Gravity squeezes the star trying to collapse it, which causes the inner core to get extremely hot and dense. This triggers nuclear fusion, and the heat and pressure from that pushes back against gravity. The two forces balance each other while a star is in its main sequence state. Easy peasy. But the details of how that works are extremely complex. Modeling the interior of a star accurately requires sophisticated computer models, and even then it can be difficult to match a model to what we see on the surface of a star. Now a new computer simulation is helping to change that.
A satellite called XRISM will use X-ray detection instruments to probe the high-energy universe like never before. Both NASA and Japan are involved in the mission.
Scotland's SaxaVord Spaceport is getting ready to host its first rocket launches soon. Archaeologists recently found Bronze Age remnants on the remote Shetland island by accident.
A number of entrepreneurial groups have shared their strategies to turn the moon into a hustle and bustle world of marketable services.
An advanced broadband satellite providing high-speed internet services that demonstrate next-generation 5G connectivity has passed its initial in-orbit tests.
We have discovered more than 5,400 planets in the universe. These worlds range from hot jovians that closely orbit their star to warm ocean worlds to cold gas giants. While we know they are there, we don’t know much about them. Characteristics such as mass and size are fairly straightforward to measure, but other properties such as temperature and atmospheric composition are more difficult. So the next generation of telescopes will try to capture that information, including one proposed telescope from the Chinese National Space Administration.

In a launch market dominated by SpaceX, Rocket Lab continues to cement its place in the orbital delivery landscape with plans for the 40th launch of its Electon rocket early Sunday.
What do you get when a hot young world orbits a wildly unstable young red dwarf? For AU Microsopii b, the answer is: flares from the star tearing away the atmosphere. That catastrophic loss happens in fits and starts, “hiccuping” out its atmosphere at one point and then losing practically none the next.

SpaceX launched the world’s heaviest commercial communications satellite atop a Falcon Heavy rocket on Friday. The triple-core rocket lifted off from Kennedy Space Center’s pad 39A with the Jupiter 3/EchoStar 24 satellite at 11:04 p.m. EDT (0304 UTC Saturday).
Marvel Studios dropped new trailer for "The Marvels"
Earth has held a stable orbit for over 4 billion years but what would happen if we changed Earth's orbit so to avoid the sun's violent demise?
Rocket Lab will launch an Earth-observing radar satellite for the company Capella Space early Sunday morning (July 30), and you can watch the action live.
An Indian PSLV rocket will launch seven satellites to orbit today (July 29), and you can watch the liftoff live.
