Astronomers discover metal-poor globular cluster by chance

An international team of astronomers led by Soren Larsen (Radboud University, Nijmegen, The Netherlands) has accidentally discovered a globular cluster that contains extremely few metals, those elements heavier than hydrogen ...

Apertif images yield first scientific results

Using Apertif (APERture Tile In Focus), searching at a radio frequency of 1.4 GHz, researchers have found an intra-hour variable (IHV) source, described in the paper "Extreme intra-hour variability of the radio source J1402+5347 ...

Planets must be formed early, study finds

Scientists have found evidence that planets form in a blink of an eye on a cosmic scale. New results, obtained using the combined power of Atacama Large Millimeter/submillimeter Array (ALMA) and Very Large Array (VLA), show ...

Researchers observe iron in exoplanetary atmosphere

An international team of researchers, led by astronomers from the University of Amsterdam, has directly demonstrated the presence of iron in the atmosphere of an exoplanet for the first time. The researchers discovered emission ...

Time symmetry and the laws of physics

If three or more objects move around each other, history cannot be reversed. That is the conclusion of an international team of researchers based on computer simulations of three black holes orbiting each other. The researchers, ...

LOFAR pioneers new way to study exoplanet environments

sing the Dutch-led Low Frequency Array (LOFAR) radio telescope, astronomers have discovered unusual radio waves coming from the nearby red dwarf star GJ1151. The radio waves bear the tell-tale signature of aurorae caused ...

Astronomers discover potential near earth objects

Three astronomers from Leiden University (the Netherlands) have shown that some asteroids that are considered harmless for now can collide with the earth in the future. They did their research with the help of an artificial ...

Star formation may be halted by cold ionized hydrogen

For the first time ionized hydrogen has been detected at the lowest frequency ever towards the center of our Galaxy. The findings originate from a cloud that is both very cold (around -230 degrees Celsius) and also ionized, ...
