Peeking around cosmic corners
Peeking around cosmic corners
Research news Using galaxies as giant gravitational lenses, an international group of astronomers headed by Max Planck@TUM tenure track professor Sherry Suyu measured independently how fast the Universe is expanding. The newly measured expansion rate for the local Universe is consistent with earlier findings.

Rapid gas flares discovered in white dwarf star for the first time
In February 2016 the dwarf nova SS Cyg anomalous outburst lasted for more than 3 weeks. Rapid radio flaring was seen throughout the outburst and the most intriguing behaviour was towards the end of the outburst, where a fast, luminous, giant flare, peaking at ~20 mJy and lasting for 15 minutes was observed.

Early arrival of water on Earth: Findings of planetologists in Münster contradict hypothesis of a late cometary origin / Publication in "Nature"
Water on Earth is the precondition for life as we know it. But where does it come from, and how long has it been here? Scientists currently discuss two possibilities: Either water was here at an early stage, during the main phase of Earth's formation, or Earth was initially completely dry and water only arrived later - through the impacts of comets or ‘wet' asteroids originating from the outer areas of the solar system.

Experiments Call Origin of Earth’s Iron into Question
An infographic describing theories on how the Earth got its iron signature. Designed by Laura Martin/The University of Texas at Austin Jackson School of Geosciences. Images 1 and 2 from NASA/JPL-Caltech, Image 3 from X-Science, Earth from NASA/JPL. AUSTIN, Texas - New research from The University of Texas at Austin reveals that the Earth's unique iron composition isn't linked to the formation of the planet's core, calling into question a prevailing theory about the events that shaped our planet during its earliest years.

Bursts of methane may have warmed early Mars
The presence of water on ancient Mars is a paradox. There's plenty of geographical evidence that rivers periodically flowed across the planet's surface. Yet in the time period when these waters are supposed to have run - three to four billion years ago - Mars should have been too cold to support liquid water.  So how did it stay so warm?

Rare meteorites challenge our understanding of the solar system
Rare meteorites challenge our understanding of the solar system
Researchers have discovered minerals from 43 meteorites that landed on Earth 470 million years ago. More than half of the mineral grains are from meteorites completely unknown or very rare in today's meteorite flow. These findings mean that we will probably need to revise our current understanding of the history and development of the solar system.

Experiment resolves mystery about wind flows on Jupiter
Experiment resolves mystery about wind flows on Jupiter
Using a spinning table and a massive garbage can, UCLA geophysicist leads team in simulating the planet's atmosphere Katherine Kornei Jupiter's colorful, swirling winds known as “jets? have long puzzled astronomers. One mystery has been whether the jets exist only in the planet's upper atmosphere — much like the Earth's own jet streams — or whether they plunge into Jupiter's gaseous interior.

Spontaneous "dust traps": the missing link in planet formation discovered
Formation mechanism of spontaneous dust traps(red) in a protoplanetary disk after the formation of a spontaneous dust trap, visible as a bright dust ring. JF Gonzalez? One of the major questions in astronomy today is how do planets form? Until recently, no theory has been able to provide a complete answer.

Hunting hidden supermassive black holes
Hunting hidden supermassive black holes
Monster black holes sometimes play a cosmic game of hide and seek, shrouding themselves from view behind giant clouds of gas and dust, according to new research. Scientists believe supermassive black holes lurk at the centres of most big galaxies, but many are hidden from the view of most telescopes.

The Case of the 'Missing Link' Neutron Star
The Case of the ’Missing Link’ Neutron Star
Like anthropologists piecing together the human family tree, astronomers have found that a misfit "skeleton" of a star may link two different kinds of stellar remains. The mysterious object, called PSR J1119-6127, has been caught behaving like two distinct objects'a radio pulsar and a magnetar'and could be important to understanding their evolution.

Fast radio burst tied to distant dwarf galaxy and, perhaps, magnetar
Fast radio burst tied to distant dwarf galaxy and, perhaps, magnetar
One of the rare and brief bursts of cosmic radio waves that have puzzled astronomers since they were first detected nearly 10 years ago has finally been tied to a source: an older dwarf galaxy more than 3 billion light years from Earth. Fast radio bursts, which flash for just a few milliseconds, created a stir among astronomers because they seemed to be coming from outside our galaxy, which means they would have to be very powerful to be seen from Earth, and because none of those first observed were ever seen again.

Homing in on source of mysterious cosmic radio bursts
Astronomers have pinpointed for the first time the home galaxy of a Fast Radio Burst, moving scientists a step closer to detecting what causes these powerful but fleeting pulses of radio waves. FRBs, which last just a few thousandths of a second, have puzzled astrophysicists since their discovery a decade ago.

Research reinforces role of supernovae in clocking the universe
How much light does a supernova shed on the history of universe? New research by cosmologists at the University of Chicago and Wayne State University confirms the accuracy of Type Ia supernovae in measuring the pace at which the universe expands. The findings support a widely held theory that the expansion of the universe is accelerating and such acceleration is attributable to a mysterious force known as dark energy.
