Black holes. Despite their names, the enigmatic objects are opposite of vacuous. They are some of the universe’s densest objects, with masses ranging from the size of stars to several hundred million stars. Their gravitational fields are so intense that not even light can escape them at a certain point, leaving us…
Plasma could be wrangled to collide photons and yield matter, according to physicists who ran simulations to explore the practical applications of a world-famous equation.
It’s not yet December, but NASA is already in a festive mood: the Webb and Hubble space telescopes recently imaged MACS0416, a pair of colliding galaxy clusters 4.3 billion light-years from Earth that is bedecked in sparkling lights.
Earlier this morning, ESA released the Euclid space telescope’s first scientific images, offering a glimpse into its mission to explore the “dark universe”—the mysterious 95% of the cosmos made up of dark matter and dark energy.
The European Space Agency’s $1.4 billion Euclid space telescope is charged with revealing the dark universe—the 95% of the cosmos we don’t see. On Tuesday, the telescope’s first images will be revealed live.
Despite a rough start to its six year mission, the Euclid space telescope is ending its commissioning phase on a high after finally being able to find its guide stars again.
The European Space Agency’s Euclid space telescope launched from Earth on July 1 and has since been getting set up to begin its investigation of the dark universe.
Behold a galactic onion: the shell galaxy NGC 3923, spotted by the Cerro Tololo Inter-American Observatory’s Dark Energy Camera (DECam) at a distance of about 70 million light-years from Earth.
The Hubble Space Telescope is no spring chicken, having operated in space for over 30 years. But the veteran observatory soldiers on. It recently imaged a massive galaxy cluster that could hold secrets about both dark and ordinary matter.
When theoretical physicists like myself say that we’re studying why the universe exists, we sound like philosophers. But new data collected by researchers using Japan’s Subaru telescope has revealed insights into that very question.
