NOW you see it, now you don’t. A giant hole in the cosmos that shocked astrophysicists last year may not exist after all. A re-examination of the area has found that the ‘void’, which supposedly contained far fewer stars and galaxies than expected, could be a statistical artefact.
The apparent void was spotted by Lawrence Rudnick […]

The sun’s movement through the Milky Way regularly sends comets hurtling into the inner solar system – coinciding with mass life extinctions on earth, a new study claims.
Scientists at the Cardiff Centre for Astrobiology built a computer model of our solar system’s movement and found that it “bounces” up and down through the plane of […]

Interacting galaxies are found throughout the Universe, sometimes as dramatic collisions that trigger bursts of star formation, on other occasions as stealthy mergers that result in new galaxies. A series of 59 new images of colliding galaxies has been released from the several terabytes of archived raw images from the NASA/ESA Hubble Space Telescope to […]

At the cores of many galaxies, supermassive black holes expel powerful jets of particles at nearly the speed of light. Just how they perform this feat has long been one of the mysteries of astrophysics. The leading theory says the particles are accelerated by tightly-twisted magnetic fields close to the black […]

Data from the ESA/NASA spacecraft SOHO shows clearly that powerful starquakes ripple around the Sun in the wake of mighty solar flares that explode above its surface. The observations give solar physicists new insight into a long-running solar mystery and may even provide a way of studying other stars.
The outermost quarter of the Sun’s interior […]

Scientists have developed a new way of determining the size and frequency of meteorites that have collided with Earth.
Their work shows that the size of the meteorite that likely plummeted to Earth at the time of the Cretaceous-Tertiary (K-T) boundary 65 million years ago was four to six kilometers in diameter. The meteorite was the […]

Spanish and UCL (University College London) scientists have discovered a possible terrestrial-type planet orbiting a star in the constellation of Leo. The new planet, which lies at a distance of 30 light years from the Earth, has a mass five times that of our planet but is the smallest found to date. One full day […]

Using a new technique, two NASA scientists have identified the lightest known black hole. With a mass only about 3.8 times greater than our Sun and a diameter of only 15 miles, the black hole lies very close to the minimum size predicted for black holes that originate from dying stars.
“This black hole is really […]

Researchers funded by the National Science Foundation (NSF) announced today in Astrophysical Journal Letters that they have discovered a faraway binary star system that could be the progenitor of a rare type of supernova.
The two yellow stars, which orbit each other and even share a large amount of stellar material, resemble a peanut. The Ohio […]
