'How do massive stars form?' is one of the fundamental questions in modern astrophysics, because these massive stars govern the energy budget of their host galaxies. Using numerical simulations, researchers revealed new components of the formation of massive stars, which were already known from the formation process of low-mass as well as primordial stars.
Never before have astrophysicists measured light of such high energy from a celestial object so far away. Around 7 billion years ago, a huge explosion occurred at the black hole in the center of a galaxy. This was followed by a burst of high-intensity gamma rays. A number of telescopes have succeeded in capturing this light.
A sensing technique that the U.S. military currently uses to remotely monitor the air to detect potentially life-threatening chemicals, toxins, and pathogens has inspired a new instrument that could 'sniff' for life on Mars and other targets in the solar system - the Bio-Indicator Lidar Instrument, or BILI.
A team of researchers have presented a new model for the origin of Saturn's rings based on results of computer simulations. The results of the simulations are also applicable to rings of other giant planets and explain the compositional differences between the rings of Saturn and Uranus.
Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery, in the late 1990s, that the universe is expanding at an accelerating pace. Now, a team of scientists has cast doubt on this standard cosmological concept.
Planet Nine the undiscovered planet at the edge of the solar system that was predicted by the work of Caltech's Konstantin Batygin and Mike Brown in January 2016 appears to be responsible for the unusual tilt of the Sun, according to a new study.
Astronomers have discovered a system consisting of two stars with three rotating planet-forming accretion discs around them. It is a binary star where each star has its own planet-forming disc and in addition, there is one large shared disc.
A new mathematical model created by astrophysicists describes how dead stars called white dwarfs could detonate, producing a type of explosion that is instrumental to measuring the extreme distances in our universe.
