An international team of astronomers filmed a small, flashing black hole in our Milky Way using unique, specialized high-speed cameras. The stellar black hole feeds on material from a nearby star and flashes hundreds of times per second. The researchers publish their findings in the journal Monthly Notices of the Royal Astronomical Society Letters.
An international team of scientists has measured a new, higher value for the speed at which the universe expands. They used two massive galaxies as "gravitational lenses" to investigate the light from remote objects. The study was led by the Max Planck Institute for Astrophysics in Garching in Germany.
Astronomers discovered water vapor in the atmosphere of super-earth K2-18b, an exoplanet that is orbiting its host star in the habitable zone. According to scientists, k2-18b might potentially be the most habitable out of all exoplanets that have been discovered up until this day. The researchers published their findings in the science journal Nature Astronomy
Astrophysicists normally assume that huge systems like the universe, are indifferent to details of smaller systems contained within it. Scientists from the University of Hawaii at Manoa (Kevin Croker and Joel Weiner) have shown that this hypothesis can fail when it comes to compact objects that remain after the collapse and explosion of huge stars.
Space elevators are a fascinating concept as they will bring down the cost of space travel enormously. If we really want space travel to become available for the masses in the future we should invest in this concept. Two astronomers recently proposed a new concept building on the idea of a space elevator called a spaceline. Enjoy this curated article on the subject:
