By combining the power of the Hubble Space Telescope, NASA’s Spitzer Space Telescope and one of nature’s zoom lenses, astronomers have found what is probably the most distant galaxy yet seen in the universe. The object offers a peek back into a time when the Universe was only 3% of its present age of 13.7 billion years.
A new study based on data from European Space Agency’s Cluster mission shows that it is easier for the solar wind to penetrate Earth’s magnetic environment, the magnetosphere, than had previously been thought. Scientists have, for the first time, directly observed the presence of certain waves that show Earth’s atmosphere behaving more like a sieve than a barrier.
The European Space Agency's Euclid mission to explore the hidden side of the universe—dark energy and dark matter—reached an important milestone that will see it head towards full construction.
The European Space Agency (ESA) assembled a top engineering team then challenged them to devise a way for rovers to navigate on alien planets. Six months later, a fully autonomous vehicle was charting its own course through Chile's Mars-like Atacama Desert.
New images from ESA’s Mars Express show the Phlegra Montes mountain range in greater detail. The range is in a region where radar probing has indicated large volumes of water ice should be hiding below. This could be a source of water for future astronauts.
The European Space Agency’s Venus Express spacecraft has discovered an ozone layer high in the atmosphere of Venus. Ozone has only previously been detected in the atmospheres of Earth and Mars. On Earth, it is both generated by and protects life from the sun’s harmful rays, but on Mars and Venus, the effect is non-biological.
The powerful influence of the Sun and the nature of mysterious dark energy motivate ESA’s next two science missions. Solar Orbiter will venture closer to the Sun than any previous mission, and Euclid will be a space telescope designed to map out the large-scale structure of the cosmos.
The great “canyon” formed by Nili Fossae on Mars is a lot like the Dead Sea, a depressed region between two faults. But instead of a salt sea, this great rift on Mars, recently imaged in spectacular detail by the European Space Agency, is thought to be the source of elevated methane levels that have been detected by telescopes on Earth.
Using a cosmic gravitational lens, astronomers using the Hubble Space Telescope have discovered a distant galaxy whose stars were born unexpectedly early in cosmic history. So early, in fact, that its stars were born just 200 million years after the Big Bang. The discovery may help explain, in a roundabout way, the deficit of radiation that has caused the Universe to be transparent to ultraviolet light.
