The asteroid Erígone will hide the star Regulus for a few seconds next Wednesday, March 20 (in the transition of the night from March 19 to 20) when it passes close to Earth. One of the interesting details of this phenomenon will be that New York City and other areas of the northern United States will be able to observe this event with the naked eye, without the need for specialized instruments.
The NuStar (Nuclear Spectroscopic Telescope Array) telescope has captured a spectacular image of Cassiopeia A, a remnant of a star that exploded as a supernova more than 11,000 years ago. Because the supernova was so far from Earth, its light reached our planet only 350 years ago.
The PLATO mission (PLAnetary Transits and Oscillations of stars) has finally been approved by ESA within its Cosmic Vision program in which Spain participates significantly with researchers from AstroMadrid and the Institute of Astrophysics of Andalusia (IAA-CSIC). Your objective will be to search for planets that orbit relatively close stars with the intention of locating Earth-like stars, that is, habitable planets. It is the worthy successor to the Kepler mission.
On some occasion, we have all looked up at the sky on a clear country night, and we have wondered how many stars there are in the universe if we already count hundreds of them with the naked eye.
A team of astronomers has detected a millisecond pulsar at a critical stage in its evolution, when it goes from emitting pulses of X-rays to emitting radio waves. Pulsars are magnetized neutron stars, the dead cores of massive stars that exploded as a supernova when they ran out of fuel. They rotate at high speed, emitting pulses of electromagnetic radiation hundreds of times per second, like a lighthouse. And they are classified according to how they generate these emissions. Radio pulsars derive their energy from the rotation of their magnetic field, while X-ray pulsars feed on an accretion disk formed by matter ripped from a companion star.
New observations in the microwave range carried out with the ALMA array (Atacama Large Millimeter / submillimeter Array) have provided astronomers with the best view yet of a gigantic star in the process of formation inside a dark cloud. known as the Spitzer Dark Cloud (SDC) 335.579-0.292. The embryonic star, located about 11,000 light-years away, greedily devours the material that falls into the cloud. It is believed that this cloud will give birth to a very bright star, with more than 100 times the mass of the Sun. Only one in ten thousand of all the stars in the Milky Way reach such a mass.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
