Making space exploration real – on Earth

You are on a rock speeding through space. On this rock called Earth every single mineral tells you something about planetary formation. This week astronauts and space engineers will unlock the mystery of those minerals as ...

Meteorites reveal story of Martian climate

Liquid water is not stable on Mars' surface because the planet's atmosphere is too thin and temperatures are too cold. However, at one time Mars hosted a warm and wet surface environment that may have been conducive to life. ...

Mars and Earth may not have been early neighbors

A study published in the journal Earth and Planetary Science Letters posits that Mars formed in what today is the Asteroid Belt, roughly one and a half times as far from the sun as its current position, before migrating to ...

Dusty protoplanetary disks

Planetary systems form out of disks of gas and dust around young stars. How the formation proceeds, however, is complex and poorly understood. Many physical processes are involved including accretion onto the star, photoevaporation ...

Chaos in cosmos: Stars with three planet-forming discs of gas

A star with a ring of planets orbiting around it - that is the picture we know from our own solar system and from many of the thousands of exoplanets observed in recent years. But now researchers from the Niels Bohr Institute ...

Stellar activity can mimic misaligned exoplanets

The occultation of stellar active regions during the planetary transit can lead to inaccurate estimates of the characteristics of these exoplanets, especially the spin-orbit tilt angle. This was the conclusion of simulations ...
