Super star takes on black holes in jet contest

A super-dense star formed in the aftermath of a supernova explosion is shooting out powerful jets of material into space, research suggests. It was previously thought that the only objects in the Universe capable of forming such powerful jets were black holes.

Bigger, older cousin to Earth discovered

NASA's Kepler mission has confirmed the first near-Earth-size planet in the "habitable zone" around a sun-like star. This discovery and the introduction of 11 other new small habitable zone candidate planets mark another milestone in the journey to finding another "Earth."

Jupiter twin discovered around solar twin

So far, exoplanet surveys have been most sensitive to planetary systems that are populated in their inner regions by massive planets, down to a few times the mass of the Earth. This contrasts with our Solar System, where there are small rocky planets in the inner regions and gas giants like Jupiter farther out.
Article in the American Journal of Modern Physics
The study of the lateral distribution of electrons in an atmospheric cascade can lead to useful conclusions on the mass and energy of the primary cosmic particle. In this work we compare the results we get from simulations by the CORSIKA program, with the theoretical NKG function expressing the lateral distribution of electrons. We then modify the original NKG function to fit better the data of the simulation.
Astronomy Picture of the Day

    Gamma rays from galactic and extragalactic sources

    The gamma rays reaching the Earth, come from different sources that are in our galaxy or other galaxies. Theories about the origin of these rays indicate various galactic and extragalactic gamma-ray sources,
