File: The hidden worlds of the Milky Way emerge from the shadows

Floating planets, interstellar asteroids, runaway stars, wandering black holes … hundreds of billions are floating in our galaxy. Hidden stars as we begin to flush out.

Feature: Deep dive in the Mediterranean to chase the neutrino

A giant detector is being deployed in the Mediterranean, at a depth of 2500 m! Its size: 1 cubic kilometer. Its target: neutrinos. Its purpose: to tell us why matter exists. Immediate boarding with the builders.

Test: Acuter Maksy 60 Discovery telescope, a Maksutov for 135 €!

On this small 60 mm telescope, plastic dominates. Underneath its toy appearance, it hides true qualities for beginners on a very tight budget. It will be suitable for children who want to explore the Moon and the planets.

Leonardo, surprising comet

German photographer Sebastian Voltmer captured comet Leonardo, which passed 92 million kilometers from Earth on January 3, 2022. The comet has been the subject of numerous observations by amateurs and professional astronomers by the end of the year.

Star flashes

The Tess satellite, mainly known for its detection of exoplanets, has witnessed a strange phenomenon. The star TIC 400799224 is occulted irregularly, possibly by an asteroid or a dwarf planet.

False lunar cabin

The case had aroused the interest of the international media in December 2021. But the structure described as a lunar “hut” or “hut” by several Anglo-Saxon media was just a simple rock, taken 80 m away by the Yutu 2 rover.

HAL 9000 on Artemis?

During Artemis 1’s unmanned lunar mission, NASA will equip the Orion spacecraft with voice control. Tests will be performed remotely to see how the built-in computer worthy of the movie “2001 A Space Odyssey” can later help astronauts.

Finally an exomoon?

A satellite would have been discovered around the extrasolar planet Kepler 1708 b, located 5,500 light-years away. But the announcement arouses skepticism among astronomers at the Max Planck Institute. Observations with the James Webb Telescope will be necessary to confirm the existence of this first exomoune.

100% European manned flights?

The ambitions of the European Space Agency are becoming clearer. In an interview with Ciel & Espace, ESA’s Director General Josef Aschbacher insists on the need for the EU to inflate the space sector’s budget to produce fully European space equipment.

Mars carbon

The Curiosity rover continues to explore the Mars plains, 10 years after its arrival on the planet. Rocks taken from the Gale crater would have revealed traces of carbon 12, an element that can signal a trace of previous biological activity. But is this the case?

Supernova announced

Scientists have exceptionally been able to follow the last moments and the death of a massive star. They thus detected fluctuations in brightness that preceded its supernova explosion. A step towards their prediction?

JWST arrived well

The James Webb Telescope has arrived at Lagrange Point L2, 1.5 million kilometers from Earth, in the opposite direction of the Sun. His first scientific shot will be published in the summer of 2022.

Rejected Starlink stations

The municipalities of Saint-Senier-de-Beuvron in Normandy and Gravelines in Hauts-de-France have won their showdown with the giant SpaceX. Elon Musk’s company has canceled its plan to establish a Starlink relay station in the two municipalities.

A nebulous galaxy

The Hubble Space Telescope has photographed the dwarf galaxy NGC 1705. In isolation, it is also relatively young, about 12 million years old. The burst hydrogen clouds around the galactic center are reminiscent of a nebula structure.

The end of the ISS

The International Space Station was to be deployed in 2031 in the Pacific Ocean, according to a report submitted to the US Congress.

Undecided race to the Moon

If the US has relaunched a manned program for the Moon since 2017, China also wants to settle permanently on our natural satellite. Between NASA’s delays and Chinese advances, the outcome of this new race on the Moon seems increasingly undecided, as our major study reveals.

Starlinks are falling

The controversial Starlink project, which SpaceX launched in 2019, is already experiencing disappointments. Many satellites experience malfunctions after takeoff, and therefore have to perform atmospheric re-entries, visible from the ground.

Third exoplanet for Proxima

After Proxima b and c, European astronomers have traced the trace of a third telluric planet around Proxima Centauri, only 4.2 light-years from Earth. It completes its cycle in just under 5 days.

Active galaxies in profile

NGC 169 and IC 1559 are two interacting galaxies that have an active core. Photographed by the Hubble Telescope reveals the astonishing details that would be invisible if their orientation were different from Earth.

Hibernatus to Mars?

The European Space Agency is seriously studying a process thought long ago in science fiction: hibernation. The development of such a technique would actually be of great interest during six months of travel to the planet Mars.
