Bubbles from the galactic center: A key to understanding dark matter and our galaxy's past?

Fresh from giving the January Rossi Prize Lecture, the astrophysicists who discovered 2 enormous radiation bubbles in the center of our galaxy discuss what they may tell us about the Milky Way and how they could help in the search for dark matter.

Gigantic ring system around J1407b much larger, heavier than Saturn's

Astronomers have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn. The ring system - the first of its kind to be found outside our solar system - was discovered in 2012.

Swarm of microprobes to head for Jupiter

A swarm of tiny probes each with a different sensor could be fired into the clouds of Jupiter and grab data as they fall before burning up in the gas giant planet's atmosphere. The probes would last an estimated 15 minutes.

Yes, black holes exist in gravitational theories with unbounded speeds of propagation

Gravitational theories with broken Lorentz invariance have attracted a great deal of interest as they provide a test-bed of LI and offer a mechanism to improve their ultraviolet behavior, so that the theories may be renormalizable. However in such theories, particles can travel with arbitrary velocities and black holes may not exist at all. In contrast to this expectation, it has been shown that an absolute horizon exists, which traps signals despite infinitely large velocities.

New research re-creates planet formation, super-earths and giant planets in the laboratory

New laser-driven compression experiments reproduce the conditions deep inside exotic super-Earths and giant planet cores, and the conditions during the violent birth of Earth-like planets, documenting the material properties that determined planet formation and evolution processes.

Watching the birth of a comet magnetosphere

The RPC-ICA instrument onboard the Rosetta spacecraft has been watching the early stages of how a magnetosphere forms around Comet 67P Churyumov-Gerasimenko as it moves closer to the Sun along its orbit and begins to interact with the solar wind.

Black hole on a diet creates a 'changing look' quasar

Astronomers have identified the first 'changing look' quasar, a gleaming object in deep space that appears to have its own dimmer switch. The discovery may offer a glimpse into the life story of the universe's great beacons.

Stardust on ocean floor shows gold and uranium alchemy in stars much less frequent than expected

Half the heavy elements in nature are created during stellar explosions such as supernovae or star collisions. Analyzing deep-sea samples of stardust that fell to Earth over millions of years, researchers made a surprising discovery about how frequently far-away stars produce heavy elements like gold and uranium.

Inside the big wormhole (w/video)

Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel) and, if that were true, it would be 'stable and navigable'. This is the hypothesis put forward in a new study.
