Natural telescope sets new magnification record

more »
An international team of astronomers has discovered one of the most extreme instances of magnification by gravitational lensing. Using the Hubble Space Telescope to survey a sample of huge clusters of galaxies, the team found a distant galaxy, eMACSJ1341-QG-1, that is magnified 30 times thanks to the distortion of space-time created by the massive galaxy cluster dubbed eMACSJ1341.9-2441.

Astrophysicists discover planets in extragalactic galaxies using microlensing

more »
Astrophysicists have discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing -- an astronomical phenomenon and the only known method capable of discovering planets at truly great distances from the Earth among other detection techniques -- researchers were able to detect objects in extragalactic galaxies that range from the mass of the Moon to the mass of Jupiter.

Stellar winds behaving unexpectedly

more »

ESA’s XMM-Newton has spotted surprising changes in the powerful streams of gas from two massive stars, suggesting that colliding stellar winds don’t behave as expected.

New use for telecommunications networks: Helping scientists peer into deep space

more »
For the first time, researchers have demonstrated that a stable frequency reference can be reliably transmitted more than 300 kilometers over a standard fiber optic telecommunications network and used to synchronize two radio telescopes.
