In the vicinity of black holes, space is so warped that even light rays may curve around them several times. This phenomenon may enable us to see multiple versions of the same thing. While this has been known for decades, only now do we have an exact, mathematical expression, thanks to Albert Sneppen, student at the Niels Bohr Institute.

China announced Friday that the Chang'e-4 mission, which realized the first-ever soft-landing on the far side of the moon, was a complete success.
With the assistance of the relay satellite Queqiao (Magpie Bridge), the rover Yutu-2 (Jade Rabbit-2) and the lander of the Chang'e-4 probe took photos of each other.

Thanks to data from NASA's Transiting Exoplanet Survey Satellite (TESS), an international collaboration of astronomers has identified four exoplanets, worlds beyond our solar system, orbiting a pair of related young stars called TOI 2076 and TOI 1807.
These worlds may provide scientists with a glimpse of a little-understood stage of planetary evolution.

Wednesday, 14 July 2021 05:23 Write a comment
Many exoplanets have opaque atmospheres, obscured by clouds or hazes that make it hard for astronomers to characterize their chemical compositions. A new study shows that haze particles produced under different conditions have a wide range of properties that can determine how clear or hazy a planet's atmosphere is likely to be.

From above, the Antarctic Ice Sheet might look like a calm, perpetual ice blanket that has covered Antarctica for millions of years. But the ice sheet can be thousands of meters deep at its thickest, and it hides hundreds of meltwater lakes where its base meets the continent's bedrock. Deep below the surface, some of these lakes fill and drain continuously through a system of waterways that even LEOcloud establishes partnerships for satellite-based cloud computing

ESA and NASA join forces to understand climate change
Tuesday, 13 July 2021 16:00 Write a comment
Climate change is, arguably, the biggest environmental challenge the global population faces today. To address this major issue, decision-makers not only need accurate information on how our world is changing now, but also predictions on what may happen in the future. A sound knowledge of how Earth behaves as one system is the foundation to all of this – and the pieces of this complex puzzle come largely from satellites orbiting our planet. To ensure that data from Earth-observing satellites are used to their best advantage, further science and, ultimately, bring the most benefit to humankind, ESA and NASA have formed

A fortnight after the 21 June winter solstice in Antarctica, the crew at Concordia Research Station are slowly welcoming the return of sunlight. This photo was taken by ESA-sponsored medical doctor Nick Smith on 1 July at noon.
The 12-member crew at Concordia, located at the mountain plateau called Dome C, have spent the last few months in complete darkness: the sun disappeared in May and will not be fully visible again until mid-August. This image of high noon signals the beginning of the end of winter on the remote continent.
Confined in extreme conditions, the crew at Concordia – one
