A star disappears in the constellation lynx

On Thursday, January 12, you can observe a "star eclipse" in northern Germany. And even with the naked eye. Amateur astronomers are called to report their observations.

James Webb Telescope spotted the first exoplanet

In the meantime, thousands of exoplanets are known. The JWST is now also part of the ranks of the telescopes that were successful in the search for the sky bodies - and then with an almost earth -sized specimen.

Perseverance - A Year on Mars

Was or exists on Mars? The Rover

Asteroid comes closer to the earth than satellites

You can hardly get closer to the Earth without meeting it. At a distance of only about 3600 kilometers, an asteroid passed by her.

Picture book landing in the Pacific

With the Artemis mission, NASA wants to bring people to the Moon again. Now the first test flight has come to a successful end after almost 26 days in space with the landing of the Orion spacecraft in the Pacific Ocean.

The construction of the world's largest radio telescope has begun

In Australia and South Africa, a gigantic network of a few hundred thousand antennas is being built. Scientists want to research the greatest puzzles in the universe.

Mars dominates at the end of the year

December is all about the red planet: Mars reaches his opposition and is even covered by the full moon on the opposition day. At the end of the month, Merkur shows tentatively in the evening sky.

Hell, Heller, Starlink

The satellite swarms orbiting the Earth are becoming more numerous and shining increasingly brighter than stars. Astronomers fear for their science if this is not stopped.

Deep look into the atmosphere of an exoplanet

The James Webb Telescope provides spectacular insights into the atmosphere of a planet 700 light-years away. For the first time, it was able to detect sulfur dioxide on an exoplanet.

The leap second is abolished

The universal period (UTC) will no longer be regularly adapted to astronomical time in the future. Among other things, technology companies had repeatedly challenged this.

Was the red planet once blue?

From the analysis of a Martian meteorite, scientists conclude that in its youth the planet was covered by an ocean 300 meters deep. A sign of life?

The Chicxulub tsunami was as gigantic as no other

Chicxulub's impact is one of the largest disasters that the earth has ever experienced. A new study shows the huge dimensions of the tsunamis triggered.

Frontiersmen of the Solar system

The two Voyager probes have continued to travel into space than any other man-made object-and still send data after decades. But the dwindling energy supply makes an soon end of the mission inevitable.

Researchers have been feeling the black hole so far

With data from the ESA satellite GAIA, scientists have found a less than 1600 light years away from a black hole. It is circled by a sun -like star.

Is a new era dawning in neutrino astronomy?

With the help of the IceCube Neutrino Observatory, researchers have found significant indications of a cosmic source for high-energy neutrinos. It could be a breakthrough.

Uranus is in opposition

Mars is on the way to opposition and dominates the constellation Taurus. Where Mars still has to go, Uranus is already there: he reaches his opposition position in Aries on November 9th.

A partial solar eclipse in the lunch break

For about two hours on October 25, the sun darkens in the middle of the day – at least partially. Can researchers also learn something about our star in the process?

Didymos-Dimorphos now with a double tail

The darts probe hit the asteroid moon Dimorphos precisely. The Hubble telescope has now photographed one episode.

A sky of barium

Among the exotic exoplanets, WASP-76b and WASP-121b are two particularly extraordinary celestial bodies. The 56th element of the periodic table drifts in their atmosphere.
