Dark matter on the move

Scientists have found evidence that dark matter can be heated up and moved around, as a result of star formation in galaxies. The findings provide the first observational evidence for the effect known as 'dark matter heating', and give new clues as to what makes up dark matter.

Early protostar already has a warped disk

Researchers have observed, for the first time, a warped disk around an infant protostar that formed just several tens of thousands of years ago. This implies that the misalignment of planetary orbits in many planetary systems may be caused by distortions in the planet-forming disk early in their existence.

Our Universe: An expanding bubble in an extra dimension

Scientists have devised a new model for the Universe - one that may solve the enigma of dark energy. They propose a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension.

A brief history of black holes

Only since 2015 have we been able to observe these invisible astronomical bodies, which can be detected only by their gravitational attraction. The history of our hunt for these enigmatic objects traces back to the 18th century, but the crucial phase took place in a suitably dark period of human history - World War II.

Stellar corpse reveals clues to missing stardust

The origin of stardust, which makes up most of the matter in our solar system, including us, is more complicated than previously thought, according to new observations of a mysterious object 15,000 light-years from Earth.

Beyond the black hole singularity

Loop quantum gravity is opening up a new paradigm in modern physics. The theory has emerged as a leading candidate to analyze extreme cosmological and astrophysical phenomena in parts of the universe, like black holes, where the equations of general relativity cease to be useful.

Faint glow within galaxy clusters illuminates dark matter

A new look at Hubble images of galaxies could be a step toward illuminating the elusive nature of dark matter, the unobservable material that makes up the majority of the universe.

Sapphires and rubies in the sky

Astrophysicists have discovered a new, exotic class of planets outside our solar system. These super-Earths were formed at high temperatures close to their host star and contain high quantities of calcium, aluminum and their oxides - including sapphire and ruby.
