Planets around a black hole? Calculations show possibility of bizarre worlds

Theoreticians in two different fields defied the common knowledge that planets orbit stars like the Sun. They proposed the possibility of thousands of planets around a supermassive black hole.

Astronomers discover highest-energy light from a gamma-ray burst

The researchers observed a gamma-ray burst with an afterglow that featured the highest energy photons - a trillion times more energetic than visible light - ever detected in a burst.

Exoplanet axis study boosts hopes of complex life, just not next door

Astrophysicists modeled a theoretical twin of Earth into other star systems called binary systems because they have two stars. They concluded that 87% of exo-Earths one might find in binary systems should have axis tilts similarly steady to Earth's, an important ingredient for climate stability that favors the evolution of complex life.

The measurements of the expansion of the universe don't add up

Physicists use two types of measurements to calculate the expansion rate of the universe, but their results do not coincide, which may make it necessary to touch up the cosmological model.

Nearly extreme black holes which attempt to 'regrow hair' become bald again

Black holes 'have no hair': no attributes that can be used to tell them apart. Extreme black holes can have an additional property, permanent hair that is made of a massless scalar field. Nearly extreme black holes have hair that is a transient phenomenon: nearly extreme black holes that attempt to regrow hair will lose it and become bald again.

Hyper-fast star ejected by supermassive black hole

Astronomers have spotted an ultrafast star, travelling at a blistering 6 million km/h, ejected by the supermassive black hole at the heart at the Milky Way five million years ago.

Astrophysicists further refine how quickly the universe is expanding

Wielding state-of-the-art technologies and techniques, a team of astrophysicists has added a novel approach to quantifying one of the most fundamental laws of the universe.

Astronomers observe a 'sunburst' from the early universe - in 12 copies

With the powerful eyes of the Hubble Space Telescope, an international team of astronomers observed straight into the bright and hot heart of a galaxy 11 billion years old in no less than 12 multiple, gravitationally lensed images. The finding casts light onto a crucial era in our universe?s history: the epoch of reionization.

Galactic fountains and carousels: order emerging from chaos

Astronomers have unveiled the results of a newly-completed, state of the art simulation of the evolution of galaxies. It allows researchers to study in detail how galaxies form, and how they have evolved since shortly after the Big Bang. For the first time, it reveals that the geometry of the cosmic gas flows around galaxies determines galaxies? structures, and vice versa.

Black holes sometimes behave like conventional quantum systems

Astronomers have studied the emergence of generalized thermal ensembles in quantum systems with additional symmetries. As a result they found that black holes thermalize the same way ordinary matter does.

Worldwide observations confirm nearby 'lensing' exoplanet

Astronomers using telescopes around the world confirmed and characterized an exoplanet orbiting a nearby star through a rare phenomenon known as gravitational microlensing. The exoplanet has a mass similar to Neptune, but it orbits a star lighter (cooler) than the Sun at an orbital radius similar to Earth's orbital radius.
