File: Best places to observe the sky
Thanks to the new map established by the Toulouse laboratory DarkSkyLab, we have traveled to France of dark skies. In each region, amateur astronomers tell us about their best places to discover the sky. Where it is still possible to admire the Milky Way.
Report at JPL, Solar System Control Center
In Pasadena, the Jet Propulsion Laboratory conducts most US space missions. It is there, in California, that the Mars rovers take their roadmap, the James Webb Telescope sends its first images, or the veteran Voyager 1 reports.
Investigating: Milky Way’s Black Holes: What the Images Reveal
Sagittarius A*, the black hole at the center of our galaxy, now has a face! But it’s still a little unclear… For the young generation of astronomers, a new search begins.
Test: Sigma FP, external for astrophotography
Sigma’s all-new mirrorless camera has a lot going for it for celestial subjects. Astronomical photography expert Thierry Legault has tested this.

An antimatter ejector pulsar
It is not known where additional antimatter with properties opposite to those observed in space came from. Researchers think they’ve found one source of the phenomenon: a pulsar that propels antimatter for its two super-powerful jets.
Perseverance reached the edge of Jezero Crater to study an ancient river delta 3.6 billion years old. The Mars rover will now have to choose from three routes to access Delta and collect samples.
Uranus, NASA’s new star
NASA has unveiled its flagship mission for the next decade. In particular, he wants to study the composition of the atmosphere of Uranus, as well as its moons. Launch planned for 2031 and put into orbit in 2044.
Samantha is back on the ISS
New astronauts arrive at the International Space Station, including Italian Samantha Cristoforetti on her second mission. It was the private company Space X that launched them with their Falcon 9 rocket and its Crew Dragon ship.
A year after the first flight, the small Martian drone Ingenuity Perseverance photographed debris from the landing. In particular, the rover’s rear shield and the remains of its parachute.
I returned at night
European astronaut Matthias Maure has returned to Earth after six months on the ISS. He is joined by his American teammates Raja Chari and Kayla Baron, who have been selected for the Artemis lunar program. The landing takes place at night, offering rare photos.
Organic molecules in a meteorite
The discovery of molecules necessary for life in the Murchison meteorite reignites the debate over the origin of life. Thanks to a new method, thymine and cytosine, components of DNA, were discovered there.
The first image of the center of our galaxy
First image release of Sagittarius A*, the supermassive black hole at the center of our galaxy. For this unprecedented shot, it took a meeting of 300 researchers and 8 radio telescopes (see p. 56).
Starliner launches to the ISS
The 2019 failure didn’t deter Boeing. Its habitable spacecraft, the Starliner capsule, was able to dock with the ISS. She brought 360 kg of supplies for the astronauts and returned to Earth on May 25.
Betelgeuse’s dimming in winter 2019-2020 has finally been explained thanks to data from a Japanese weather satellite. The red supergiant actually undergoes a partial cooling of its surface and ejects a cloud of gas and dust.
Personal diving suit
NASA outsourced the development of its lunar spacesuits for the Artemis program to two private companies, Axiom Space and Collins Aerospace. The ceiling is $3.5 billion to build these spacesuits that will also be used on board the ISS.
Jupiter is finally verified by Europa
Toulouse Cyril Cavel with Ciel & espace, project manager of Juice, the European mission that will depart for Jupiter in April 2023. The probe’s journey will last 7.5 years, after which it will fly past the Jovian moon 35 times.
Its mission has just begun, but the James Webb Space Telescope has already been hit by a micrometeorite! One of its mirrors was broken on impact. Monitoring is not compromised.
33 million stars
For the third time, astronomers have published data collected by the European satellite Gaia. Among other results, the positions and motions of 33 million stars were determined.
To end the supermoon
A strawberry supermoon! For the June 14 full moon, a new baroque qualifier has flourished in the press. The opportunity to think that all this does not correspond to something exceptional.
Aluminum foil on Mars
At the entrance to Jezero Crater’s Fossil Delta, the Perseverance rover encountered a very curious sight: a piece of silver coating from the ship that allowed it to come to Mars…
Two recently discovered neutron stars spin much more slowly than theory predicts. So a question: have astronomers discovered a new category of these dense and compact stars?
