Astronomers catch massive galaxy assembling piece by piece 1.2 billion years after Big Bang

Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe’s largest galaxies formed. The […]

Should scientists have research ‘reserves’ on the moon?

The worlds of the solar system are exciting and, so far, mostly pristine places for planetary scientists to study. As space missions continue to travel to Mars, Europa, asteroids and other worlds, questions arise about […]

Young rift flanks suggest Venus remains tectonically active

Venus is an inhospitable place, with temperatures soaring to several hundred degrees Celsius (hundreds of degrees Fahrenheit) and no oceans like those on Earth. Planetary scientists long believed Venus was geologically dormant. However, recent research […]

Could alien signals be hiding on a different radio channel?

Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio spectrum that has not recently been explored.This post was originally published on this site

NASA’s new space telescope will tackle some of the universe’s biggest mysteries

NASA is about to launch a space observatory that could help settle some of the biggest mysteries in modern astronomy. The Nancy Grace Roman Space Telescope will study how the universe began, what it is […]

JWST captures rare glimpse of early black hole growing inside network of young galaxies

Astronomers using the James Webb Space Telescope have captured one of the clearest views yet of how an early supermassive black hole may grow within a network of young galaxies. The compact active galaxy, seen […]

Jupiter-mass ‘exomoon’ orbiting brown dwarf challenges cosmic labels

Observations made with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed evidence for a moon-like object in the CD-35 2722 system. Unlike moons in our solar system, the newly found object does […]

Astronomers are still trying to understand how a galaxy’s spiral arms form

The Whirlpool galaxy (M51) is a classic grand spiral galaxy. It was the first object identified as a spiral, way back in 1845. At the time, it and other galaxies were considered spiral nebulae, since […]

Scientists turn radio telescopes into space scanners—sharpening view of hidden orbital threats

Scientists have successfully demonstrated a breakthrough in how sensitive radio telescopes can be used to significantly improve the world’s ability to detect, track and characterize satellites and space debris in orbit.This post was originally published […]

Does dark energy really exist? Our work identifies cracks in the foundations of today’s cosmological model

According to current understanding, the universe is expanding—and is doing so at an accelerating rate. This is believed to be caused by something called the cosmological constant, which was first proposed by Albert Einstein in […]
