In the latest issue of the journal Nature, astronomers from Stockholm University reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion. Supernovae of Type Ia are important for astronomers since they are used to measure the expan

The theory of relativity works well when you want to explain cosmic-scale phenomena - such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle-scale phenomena - such as the behavior of individual electrons in an atom. But combining the two in a completely satisfactory way has yet to be achieved. The search for a "quantum theory of gravi

Astronomers have discovered an Earth-size exoplanet, or world beyond our solar system, that may be carpeted with volcanoes. Called LP 791-18 d, the planet could undergo volcanic outbursts as often as Jupiter's moon Io, the most volcanically active body in our solar system. They found and studied the planet using data from NASA's TESS (Transiting Exoplanet Survey Satellite) and retired Spit

A strong quake in the last year of the NASA Mars InSight mission, enabled researchers at ETH Zurich to determine the global thickness and density of the planet's crust. On average, the Martian crust is much thicker than the Earth's or the Moon's crust, and the planet's main source of heat is radioactive. In May 2022, the Marsquake Service at ETH Zurich recorded the largest quake ever obser

The Perseverance rover has been exploring the top of the Western fan in Jezero crater for some time now, but new observations never fail to offer new insights. Sitting at the edge of Belva crater on top of the fan, Perseverance has been investigating sediments that were transported to their location via the ancient streams that flowed into Jezero. Each unique rock, boulder, or sediment tha

Researchers have developed a new smaller, lighter design for space-based imaging spectrometers with high spectral resolution. These high-dispersion imaging spectrometers could be used onboard spacecraft or satellites to study the Earth's atmosphere or the atmospheres of other planets. James P. McGuire, Jr. from NASA's Jet Propulsion Laboratory in Southern California will present the new re

From satellites that can pinpoint the sources of industrial pollution, to others that track hurricane movements by the hour, space has emerged as a key front in the fight against climate change. New launches are - literally and metaphorically - skyrocketing, and giving rise to increased cooperation between space agencies and private companies. Among the most fruitful areas of collabora

Space traffic is a pressing issue. With over 20.000 satellites expected to be launched in the next decade, various orbits are becoming increasingly congested. The situation is especially pronounced in Low Earth Orbit (LEO). The abundance of satellites is not only responsible for "an unprecedented space traffic jam". It is also the cause of a large amount of space debris, or 'junk', which i

Gilmour Space Technologies, a leading Australian aerospace company, was honored to welcome Prime Minister Anthony Albanese to their state-of-the-art manufacturing facility today. The visit marked the official unveiling and 'launch' of the Eris rocket, Australia's inaugural domestically developed orbital launch vehicle. Prime Minister Anthony Albanese expressed his enthusiasm for this remar

A team of students and researchers are using virtual reality (VR) to bring ESA’s Argonaut lunar lander concept to life at the European Astronaut Centre.

Argonaut is a lunar lander that will deliver scientific instruments and cargo to the Moon at the end of this decade. Interns and scientists involved in the simulations are part of ESA’s Extended Reality (XR) laboratory, German Aerospace Centre DLR and the Spaceship EAC initiative.
