The heavens themselves blaze forth the death of princes."

Call with Sławosz Uznański-Wiśniewski at Paris Air Show 2025

ESO Top News - Wed, 06/18/2025 - 7:00am
Video: 00:12:58

Watch the replay of the call between Josef Aschbacher, ESA Director General, Andrius Kubilius, EU Commissioner for Defence and Space, and Sławosz Uznański-Wiśniewski, ESA project astronaut. This call took place at the Paris Air Show 2025 (Le Bourget) on 18 June. Project astronaut Uznański-Wiśniewski joined from quarantine ahead of the upcoming Ignis mission mission.

Sponsored by the Polish government and supported by ESA, the Polish Ministry of Economic Development and Technology (MRiT), and the Polish Space Agency (POLSA), the Ignis mission features an ambitious technological and scientific programme. It includes several experiments proposed by the Polish space industry and developed in cooperation with ESA, along with additional ESA-led experiments.

The Universe is Filled With Natural Telescope Lenses. Roman Will Use Them to Study Dark Matter

Universe Today - Tue, 06/17/2025 - 6:07pm

We don't know what dark matter is, but that doesn't stop astronomers from using it to their advantage. Dark matter is part of what makes gravitational lensing so effective. Astronomers expect the Roman Space Telescope to find 160,000 gravitational lenses, and dark matter makes a crucial contribution to these lenses.

How Bubble Muscles Could Help Astronauts Get Their Space Legs

Universe Today - Tue, 06/17/2025 - 6:07pm

When astronauts finally reach Mars, they'll face a unique challenge: walking and working in gravity that's only 37% as strong as Earth's. After spending months in the weightlessness of space, their weakened muscles and bones will struggle to cope with even this reduced gravity. Now, researchers at the University of Bristol have developed a promising solution; a soft, wearable exosuit powered by inflatable "bubble muscles."

The Moon is Covered in Tiny Orange Glass Beads. Now We Know Why.

Universe Today - Tue, 06/17/2025 - 6:07pm

When the Apollo astronauts landed on the Moon, they discovered drifts of tiny brilliant orange glass beads glittering across the surface. Each one less than 1 mm across and formed about 3.6 billion years ago. These microscopic treasures, each smaller than a pinhead, had been hiding their secrets for billions of years. Now, cutting edge technology has finally cracked the mystery: they're perfect time capsules from the Moon's explosive volcanic past, frozen droplets of ancient lava that solidified instantly in the airless void recording the history of the Moon.

1000 Hours with the Square Kilometre Array is Our Best Hope to Finally See Cosmic Dawn.

Universe Today - Tue, 06/17/2025 - 6:07pm

The Hubble Deep Field revolutionised astronomy by staring at a seemingly empty patch of sky for thousands of hours, unveiling a cosmos teeming with distant galaxies. But even Hubble can't peer back far enough to witness the universe's first moment of illumination; the Cosmic Dawn, when primordial darkness gave way to starlight. Now, the Square Kilometre Array promises to shatter that barrier. In a groundbreaking simulation, researchers have modelled 1000 hours of SKA observations, creating astronomy's next great deep field, one designed to capture the universe's very first sunrise.

The Solar Orbiter is Giving Us an Unprecedented Look at the Sun's Poles

Universe Today - Tue, 06/17/2025 - 6:07pm

The ecliptic is the apparent path that the Sun follows during a year. It's an imaginary line that the planets follow, with some small deviations, around the Sun. Spacecraft find it easier to follow the ecliptic because it's generally more energy efficient. However, the Solar Orbiter isn't on the ecliptic and it's giving us our first up-close looks at the Sun's poles.

Distant Galaxy Has Similar Icy Dust to the Milky Way. So, Similar Planets?

Universe Today - Tue, 06/17/2025 - 6:07pm

For most of us, dust is just something we have to clean up. For astronomers, interstellar dust is a hindrance when they want to study distant objects. However, recent James Webb Space Telescope (JWST) observations of a distant galaxy are changing that. This infrared-sensitive observatory is letting them find a way to use dust to understand the evolution of early galaxies. In addition, it uncovered a special property of that galaxy's ice-covered dust, indicating it could be similar to the materials that formed our Solar System.

Supernova Explosions Changed Earth's Climate and Shaped Humanity's History

Universe Today - Tue, 06/17/2025 - 6:07pm

Most scientists agree that supernova explosions have affected Earth's climate, though the details are not all clear. They likely cooled the climate several times in the last several thousand years, just as humanity was becoming established around the world. The evidence is in telescopes and tree rings.
