Astronomers have identified the most massive star in our home galaxy's largest stellar nursery, the star-forming region W49. The star, named W49nr1, has a mass between 100 and 180 times the mass of the Sun.
For the first time in the history of solar research, scientists have successfully measured solar energy at the instant of creation inside the sun. In the Gran Sasso underground laboratory, physicists of the Borexino Collaboration are for the first time ever directly observing the neutrinos created during the fusion of two hydrogen nuclei and the resultant production of heavy hydrogen.
Astronomers have uncovered for the first time the earliest stages of a massive galaxy forming in the young Universe. The growing galaxy core is blazing with the light of millions of newborn stars that are forming at a ferocious rate.
The field of astrophysics has a stubborn problem and it's called lithium. The quantities of lithium predicted to have resulted from the Big Bang are not actually present in stars. But the calculations are correct - a fact which has now been confirmed for the first time in experiments conducted at the underground laboratory in the Gran Sasso mountain in Italy.
An international team of astronomers using the Atacama Large Millimeter/submillimeter Array and the Karl G. Jansky Very Large Array - among other telescopes - has obtained the best view yet of a collision between two galaxies when the Universe was only half its current age.
A unique experiment at the Fermi National Accelerator Laboratory called the Holometer has started collecting data that will answer some mind-bending questions about our universe - including whether we live in a hologram.
The moon appears to be a tranquil place, but modeling by scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon's coldest craters through the process of sparking - a finding that could change our understanding of the evolution of planetary surfaces in the solar system.
The whirlpool galaxy M51 in a distance of approximately 30 million light years appears almost face-on and displays a beautiful system of spiral arms. A European team of astronomers observed M51 with the LOFAR Telescope in the frequency range 115-175 MHz and obtained the most sensitive galaxy image at frequencies below 1 GHz so far.
This image, captured by the Wide Field Imager at ESO's La Silla Observatory in Chile, shows two dramatic star formation regions in the Milky Way. The first, on the left, is dominated by the star cluster NGC 3603, located 20 000 light-years away, in the Carina-Sagittarius spiral arm of the Milky Way. The second, is a collection of glowing gas clouds known as NGC 3576 that lies about half as far from Earth.
