Rapid destruction of Earth-like atmospheres by young stars
Rapid destruction of Earth-like atmospheres by young stars
Researchers show young stars rapidly destroy Earth-like Nitrogen dominated atmospheres The discoveries of thousands of planets orbiting stars outside our solar system has made questions about the potential for life to form on these planets fundamentally important in modern science. Fundamentally important for the habitability of a planet is whether or not it can hold onto an atmosphere, which requires that the atmosphere is not completely lost early in the lifetime of the planet.

Earth vs. asteroids: humans strike back
Earth vs. asteroids: humans strike back
22 April 2019 Incoming asteroids have been scarring our home planet for billions of years. This month humankind left our own mark on an asteroid for the first time: Japan's Hayabusa2 spacecraft dropped a copper projectile at very high speed in an attempt to form a crater on asteroid Ryugu. A much bigger asteroid impact is planned for the coming decade, involving an international double-spacecraft mission.

New satellite data sets reveal flood risk for vulnerable populations
Scientists from the University of Bristol have modelled the likelihood of flooding in some of the world's most hazardous zones to an unparalleled degree of accuracy. Their insights could help people and governments better protect themselves against risk and flood losses. As reported today (Thursday 18 April), experts in flood risk and environmental uncertainty analysed detailed hazard maps of 18 countries across Latin America, Asia and Africa against data developed by Facebook's Connectivity Labs detailing population density in those countries.

Scientists invent way to trap mysterious ’dark world’ particle at Large Hadron Collider
Now that they've identified the Higgs boson, scientists at the Large Hadron Collider have set their sights on an even more elusive target. All around us is dark matter and dark energy-the invisible stuff that binds the galaxy together, but which no one has been able to directly detect. "We know for sure there's a dark world, and there's more energy in it than there is in ours," said LianTao Wang, a University of Chicago professor of physics who studies how to find signals in large particle accelerators like the LHC.

Five planets revealed after 20 years of observation
Five planets revealed after 20 years of observation
A team of astronomers led by the UNIGE has discovered five new planets with periods of revolution between 15 and 40 years. It took 20 years of regular observations to achieve this result. Over 4000 exoplanets have been discovered since the first one in 1995, but the vast majority of them orbit their stars with relatively short periods of revolution.

NASA Twin Study Provides a Multi-omics View of the Human Body’s Response to a Year in Space
As part of the unprecedented NASA Twin study, researchers at University of California San Diego School of Medicine examined how long-term space flight affects the regulation of proteins and metabolites in the body and the implications for cardiovascular health and vision, both during and after space travel.

First results from the ExoMars Trace Gas Orbiter
First results from the ExoMars Trace Gas Orbiter
10 April 2019 New evidence of the impact of the recent planet-encompassing dust storm on water in the atmosphere, and a surprising lack of methane, are among the scientific highlights of the ExoMars Trace Gas Orbiter's first year in orbit. Two papers are published in the journal Nature today describing the new results, and reported in a dedicated press briefing at the European Geosciences Union in Vienna.

First image of a black hole
First image of a black hole
The Event Horizon Telescope (EHT) - a planet-scale array of eight ground-based radio telescopes forged through international collaboration - was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.

Working together as a
Working together as a "virtual telescope," observatories around the world produce first direct images of a black hole
Images reveal supermassive black hole at the heart of the Messier 87 galaxy. Haystack research scientist speaks with Lowell Sun reporter Alana Melanson about how scientists at the Haystack Observatory made key contributions to creating the first-ever image of a black hole. "It's enormous volumes of data coming at you very, very fast - much faster than you can record on a single hard drive," says Fish of the vast quantities of data processed at Haystack to develop the image.

Predicting "killer" electrons in the Earth's outer radiation belt protects spacecraft An artist's rendering of the Van Allen radiation belts surrounding Earth. The purple, concentric shells represent the inner and outer belts. They completely encircle Earth, but have been cut away in this image to show detail.

Are Brown Dwarfs Failed Stars Or Super-Planets?
Are Brown Dwarfs Failed Stars Or Super-Planets?
Brown dwarfs fill the 'gap' between stars and the numerous smaller planets ' two very different types of astronomical objects. But how they originate has yet to be fully explained. Astronomers from Heidelberg University may now be able to answer that question. They discovered that the star Îoe Ophiuchi in the Milky Way is being orbited by two brown dwarfs, which in all probability formed along with the star from a gas and dust disk, just as planets do.

Fireworks of blue lightning and gamma rays above thunderclouds
9 April 2019 After only one year in space, the Atmosphere-Space Interactions Monitor (ASIM) on the International Space Station has given researchers a new understanding of how lightning is created, and how thunderstorms can affect the atmosphere and the climate. The first measurements from the facility that is flying 400 km above Earth outside Europe's Columbus laboratory, reveal how so-called 'terrestrial gamma-flashes' form in the atmosphere.

Music for space
Music for space
5 April 2019 Music has long been known to affect people's mood. A certain tune can lift you up or bring you to tears, make you focus, relax or even run faster. Now a study is investigating how the power of music may improve human performance in one of the most stressful and alien environments we know - space.

Preserving heritage data at ESA
5 April 2019 Why is archiving and curating heritage satellite data so fundamentally important? How can heritage data from old satellites be used to compare with current findings? This week, ESA is focusing on its core Basic Activities, which, for Earth observation and other directorates, include preserving precious data.

Self-driving spacecraft set for planetary defence expedition
Self-driving spacecraft set for planetary defence expedition
5 April 2019 Engineers designing ESA's Hera planetary defence mission to the Didymos asteroid pair are developing advanced technology to let the spacecraft steer itself through space, taking a similar approach to self-driving cars. "If you think self-driving cars are the future on Earth, then Hera is the pioneer of autonomy in deep space," explains Paolo Martino, lead systems engineer of ESA's proposed Hera mission.

Why elite cyclists should talk to astronauts
It is well known that the bones of astronauts can become weak from being in space. But did you know that elite cyclists can lose a similar amount of bone density during a racing season? A new study by our sports science experts has found that something called Relative Energy Deficiency in Sports (RED-S) is the main culprit.

Mars Express matches methane spike measured by Curiosity
Mars Express matches methane spike measured by Curiosity
1 April 2019 A reanalysis of data collected by ESA's Mars Express during the first 20 months of NASA's Curiosity mission found one case of correlated methane detection, the first time an in-situ measurement has been independently confirmed from orbit. Reports of methane in the martian atmosphere have been intensely debated, with Mars Express contributing one of the first measurements from orbit in 2004, shortly after its arrival at the Red Planet.
