The European Space Agency is developing its own reusable spacecraft. Space Rider will be an un-crewed vehicle with high-tech capabilities that will provide access to space for scientific and commercial enterprises.
Scientists studying data from the ESA Gaia spacecraft have discovered a previously unknown dwarf galaxy lurking just outside the Milky Way, an extremely low-density swarm of stars two thirds the size of Earth’s galaxy.
More precisely, the Milky Way collided with the second galaxy, absorbing many of its stars and spiraling out a chaotic tangle of stellar matter — birthing new stars and altering the orbits of others.
The project is only the second, after NASA’s MESSENGER mission, to attempt putting a spacecraft into orbit around the solar system’s innermost planet and is one of the most technically challenging missions.
Astronomers report the first detection of matter falling into a black hole at 30% of the speed of light, located in the center of the billion-light year distant galaxy PG211+143.
To help us grok the immensity of the cosmos, the European Space Agency has released a remarkable image of space in which every point is an entire galaxy.
The European Space Agency’s Gaia spacecraft has produced the most accurate star catalogue ever assembled, including high-precision measurements of the brightness and positions of some 1.7 billion stars.
The novel European Space Agency technology would scoop up atmospheric nitrogen and oxygen during near-Earth orbits and turn it into fuel.
The European Space Agency picked the Atmospheric Remote-sensing Infrared Exoplanet Large-survey (ARIEL) mission to explore the nature of exoplanets.
They say the shortest distance between two points is a straight line, but for JUICE—a European Space Agency-led, Jupiter-bound probe scheduled to launch in 2022.
