Matière noire : des milliards de Wimps traverseraient notre corps chaque seconde. Douter de l’existence de la matière noire ne semble pas rationnel, bien qu’une preuve directe et indiscutable nous manque encore. Selon deux astrophysiciens, il se pourrait que des milliards de particules de matière noire, des Wimps plus précisément, traversent notre corps chaque seconde. On ne le répétera probablement jamais assez : on dispose de preuves solides, bien qu’indirectes, de l’existence de la matière noire . On ne peut cependant pas en conclure que nous savons vraiment que plus de 20 % de la masse contenue dans un large volume de l’univers observable est constituée de particules de matière encore jamais observées sur Terre.

Spännande och dramatisk är svaret. Nya mätningar med Hubbleteleskopet bekräftar att Vintergatan kommer inom bara några miljarder år att gå samman med vår närmaste granne, Andromedagalaxen, även känd som M31.

Hubble épingle 7 galaxies aux frontières de l'Univers. Le télescope spatial Hubble a découvert 7 galaxies si lointaines que leur lumière a mis plus de 13 milliards d'années à nous parvenir. L'Univers ayant 13,7 milliards d'années, nous les observons telles qu'elles étaient lorsque celui-ci n'avait que 3% de son âge actuel. By Linda HerridgeNASA's John F.

EDT Wednesday, July 20. The crew entered to document the interior and will begin unloading cargo this afternoon. The spacecraft delivered nearly 5,000 pounds of science, hardware and supplies, including instruments to perform the first-ever DNA sequencing in space, and the first of two identical international docking adapters (IDA). Human technology has advanced significantly over the past 5,000 years, and the Earth bears the scars to prove it.

We've altered the landscape, the climate and the biological diversity. We've erected skyscrapers for the living and colossal tombs for the dead. Perhaps most important, we've learned to harness a portion of the planet's energy, but we still thirst for so much more power. This insatiable appetite for energy will continue to chart the course of human civilization in the 5,000 years to come. AIM at Didymos ESA’s proposed Asteroid Impact Mission and its twin CubeSats, with its microlander in place on the smaller of the two Didymos asteroids.

ESA performs a wide variety of asteroid research, and is participating in international Asteroid Day tomorrow. Aurora Australis ESA astronaut Tim Peake posted this stunning image on his social media channels, commenting: "Station passed through magnificent aurora Australis last night.

" Tim is set to return to Earth on 18 June 2016, bringing his six-month Principia mission to the ISS to an end. Description This multicoloured swirl of yellow and blue shows a prominent ring of gas near the North Celestial Pole.

The pole appears to be fixed in place, while the rest of the night sky slowly circles around it because of Earth’s rotation. This image comes courtesy of ESA’s Planck satellite, which spent years mapping the entire sky in exquisite detail between 2009 and 2013.The North Celestial Loop lies over 325 light-years away from us towards the constellation of Ursa Major (The Great Bear). It is composed of dust and neutral hydrogen blown and sculpted into an expanding shell. The first two images above show the central portions of galaxy M82 prior to the supernova explosion, while the right image shows Supernova SN2014J taken by the FLITECAM instrument on the SOFIA observatory on Feb. 20.

Credits: NASA/SOFIA/FLITECAM team / Sachindev Shenoy On four flights in late February, NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) focused on an explosion known as a supernova that obliterated the remains of a star about the mass of the sun in the Messier 82 galaxy (M82). Located 11 million light years from Earth in the direction of the constellation Ursa Major, the exploding star is named Supernova (SN) 2014J. NASA called upon SOFIA to view the supernova on Feb. 18, 20, 24 and 26 using the converted jetliner's 2.5-meter diameter telescope that is optimized for collecting radiation at infrared wavelengths.

Supernova 2014J is a Type 1a supernova, known to astronomers as a "standard candle. " A mysterious ring of microwaves Fifty years ago, astronomers discovered a mystery. They called it Loop I. Today, we still have not fully resolved the mystery of how this giant celestial structure formed but we do now have the best image of it, thanks to ESA’s Planck satellite. Loop I is a nearly circular formation that covers one third of the sky. In reality, it is probably a spherical ‘bubble’ that stretches to more than 100º across, making it wider than 200 full Moons. What they do know is that the structure shows up in many different wavelengths, from radio waves to gamma rays. Inicio de sesión. Yahoo - Inicio de sesión. Galileo liftoff And yet it moves: 14 Galileo satellites now in orbit 24 May 2016 Named for the astronomer who pinpointed Earth’s true position in the Solar System, the Galileo satellite navigation system that will help Europe find its way in the 21st century now has 14 satellites in orbit after today’s double launch.

Galileos 13 and 14 lifted off together at 08:48 GMT (10:48 CEST, 05:48 local time) atop a Soyuz rocket from French Guiana.

Alexander Gerst to be Space Station commander 18 May 2016 ESA astronaut Alexander Gerst has been assigned a new mission to the International Space Station, where he will fulfil the role of commander during the second part of his six-month mission in 2018. The news was announced today in the presence of German Chancellor Angela Merkel by ESA Director General Jan Woerner at the European Astronaut Centre in Cologne, Germany. Alexander worked on the Station for six months on his Blue Dot mission in 2014. Models of Proba-3 designs The design evolution of ESA’s Proba-3 double satellite is shown by this trio of 3D-printed models, each pair – from left to right – produced after successive development milestones.

“These paired models, 3D printed in plastic, were not made for show,” explains Agnes Mestreau-Garreau, ESA’s project manager. “Instead, they’re used almost daily. The fourth SpaceX cargo mission to the International Space Station (ISS) under NASA's Commercial Resupply Services contract is scheduled to launch Saturday, Sept. 20, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. The one-day adjustment in the launch date was made to accommodate preparations of the SpaceX Falcon 9 rocket and was coordinated with the station’s partners and managers. The company's Falcon 9 rocket, carrying its Dragon cargo spacecraft loaded with more than 5,000 pounds of scientific experiments and supplies, will lift off at 2:16 a.m.
