Revealing the black hole at the heart of the galaxy

Including the powerful ALMA into an array of telescopes for the first time, astronomers have found that the emission from the supermassive black hole Sagittarius A* at the center of the galaxy comes from a smaller region ...

Verlinde's new theory of gravity passes first test

A team led by astronomer Margot Brouwer (Leiden Observatory, The Netherlands) has tested the new theory of theoretical physicist Erik Verlinde (University of Amsterdam) for the first time through the lensing effect of gravity. ...

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, ...

Planet formation starts before star reaches maturity

A European team of astronomers has discovered that dust particles around a star already coagulate before the star is fully grown. Dust particle growth is the first step in the formation of planets. The researchers from the ...

Dutch astronomers photograph possible toddler planet by chance

An international team of astronomers headed by Dutch researchers from Leiden University has coincidently found a small companion around the young double star CS Cha. The astronomers examined the dust disc of the binary, while ...

Asteroids and comets shower Mars with organics

Asteroids and comets appear to be a much more important supplier of organic molecules on Mars than expected. Until now, astronomers assumed that the organics on Mars mainly came from dust particles from space. Now, computer ...

Habitable planets around pulsars theoretically possible

It is theoretically possible that habitable planets exist around pulsars. Such planets must have an enormous atmosphere that convert the deadly X-rays and high energy particles of the pulsar into heat. This is the conclusion ...

Neutron star with strong magnetic field may still launch jets

An international team of astronomers led by the University of Amsterdam (The Netherlands) suspects that neutron stars with a strong magnetic field can still launch so-called jets. Since the 1980s, it was thought that strong ...
