This year’s Nobel Prize in Physics has been awarded to three physicists — Pierre Agostini at Ohio State University in Columbus, Ferenc Krausz at the Max Planck Institute of Quantum Optics in Garching, Germany, and Anne L’Huillier at Lund University, Sweden — for their research into attosecond pulses of light.Attosecond physics allows scientists to look

Large constellations of bright artificial satellites in low Earth orbit (LEO) pose significant challenges to ground-based astronomy. Current orbiting constellation satellites have brightness’s between apparent magnitudes 4 and 6. Satellite operators, astronomers, and other users of the night sky are working on brightness mitigation strategies. Radio emissions induce further potential risk to ground-based radio telescopes

The Sun’s position in the sky changes when looked at during the same time each day from the same location throughout the year. The video is showing how the Sun changes its position in the sky in two months. This phenomenon is called as Analemma.

The Psyche mission is a journey to a unique metal-rich asteroid orbiting the Sun between Mars and Jupiter. What makes the asteroid Psyche unique is that it appears to be the exposed nickel-iron core of an early planet, one of the building blocks of our solar system.

The ISS’s fiery death will likely occur in three phases: Solar array and radiator separationBreakup of intact modules and the truss segmentIndividual module fragmentation and loss of truss structural integrity After that, the external skin of the modules will melt away, heating and disintegrating the internal hardware. Most hardware will likely burn up during the
Many neutron stars are likely undetectable because they simply do not emit enough radiation. However, under certain conditions, they can be easily observed. A handful of neutron stars have been found sitting at the centers of supernova remnants quietly emitting X-rays. More often, though, neutron stars are found spinning wildly with extreme magnetic fields as
The creation of our universe has always puzzled the astronomers. How can something infinite start from nothing? What was before this universe? Or after this? Is this the only universe or there are multiverses? Early on, scientists believed in a static Universe, but evidence began to suggest that the Universe was expanding. The Big Bang

Galaxies are vast cosmic islands of stars, gas, dust, and dark matter held together by gravity. Hubble’s keen eye has revealed intricate details of the shapes, structures, and histories of galaxies — whether alone, as part of small groups, or within immense clusters. From supermassive black holes at galactic centers to giant bursts of star
