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.

New model accurately predicts harmful space weather
New model accurately predicts harmful space weather
Predicting "killer" electrons in the Earth's outer radiation belt protects spacecraft The more research and refinements we do, the increased potential for us to have more reliable forecasts with longer warning time before the arrival of new killer electrons. Yue Chen LOS ALAMOS, N.M., April 9, 2019- A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation belt.

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
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
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.

Dark Energy Instrument’s Lenses See the Night Sky for the First Time
DESI project reaches important milestone in successfully demonstrating precise focusing, alignment of its lens assembly On April 1, the dome of the Mayall Telescope near Tucson, Arizona, opened to the night sky, and starlight poured through the assembly of six large lenses that were carefully packaged and aligned for a new instrument that will launch later this year.

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.

Cassini mission reveals the secrets of Saturn’s walnut-shaped ring moons
New study in in the high-ranking journal Science No 73/2019 from Mar 29, 2019 A new study of Saturn's small inner moons was published in the high-ranking journal Science . Images of Pan, Daphnis, Atlas, Pandora and Epimetheus, obtained by the Cassini spacecraft in winter 2016/17, show that several of these so-called "shepherd moons" exhibit huge ridges around their equators, giving them a very peculiar and impressing walnut-like shape (Fig.

How to use gravitational waves to measure the expansion of the universe
On the morning of Aug. 17, 2017, after traveling for more than a hundred million years, the aftershocks from a massive collision in a galaxy far, far away finally reached Earth. These ripples in the fabric of spacetime, called gravitational waves, tripped alarms at two ultra-sensitive detectors called LIGO, sending texts flying and scientists scrambling.

Rivers raged on Mars late into its history
Long ago on Mars, water carved deep riverbeds into the planet's surface-but we still don't know what kind of weather fed them. Scientists aren't sure, because their understanding of the Martian climate billions of years ago remains incomplete. A new study by University of Chicago scientists catalogued these rivers to conclude that significant river runoff persisted on Mars later into its history than previously thought.

Mars calling
An exciting new competition is giving citizens of planet Earth the opportunity to get their voices to Mars in the next phase of the ExoMars programme. The ExoMars rover and platform will launch to the Red Planet in 2020. The joint ESA-Roscosmos mission will investigate, among other things, signs of lightning on Mars using a scientific instrument mounted on the Kazachok surface platform, which arrived to Europe from Russia this week for final assembly.

Detectors set to resume hunt for gravitational waves
University of Glasgow astrophysicists are gearing up to resume the search for gravitational waves, the ripples in spacetime caused by some of the universe's most spectacular events. The Glasgow researchers played key roles in the development of the National Science Foundation's Advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) project, based in the United States, which will be starting a new science run on Monday April 1 along with the Virgo gravitational detector, based in Italy.

Testing the value of artificial gravity for astronaut health
Test subjects in Cologne, Germany will take to their beds for 60 days from 25 March as part of a groundbreaking study, funded by European Space Agency ESA and US space agency NASA, into how artificial gravity could help astronauts stay healthy in space. Carried out at the German Aerospace Center's (DLR) :envihab facility, the long-term bedrest study is the first of its kind to be conducted in partnership between the two agencies.
