Two large asteroids safely pass Earth just 42 hours apart

Two large asteroids will safely pass Earth this week, a rare occurrence perfectly timed to commemorate this year’s Asteroid Day . Neither poses any risk to our planet, but one of them was only discovered a week ago, highlighting the need to continue improving our ability to detect potentially hazardous objects in our cosmic neighbourhood. To […]

Webb snaps first image of aligned jets from newborn stars

For the first time, a phenomenon astronomers have long hoped to image directly has been captured by the NASA/ESA/CSA James Webb Space Telescope’s Near-InfraRed Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area of this young, nearby star-forming region. To source

Too young to be so cool: lessons from three neutron stars

ESA’s XMM-Newton and NASA’s Chandra spacecraft have detected three young neutron stars that are unusually cold for their age. By comparing their properties to different neutron star models, scientists conclude that the oddballs’ low temperatures disqualify around 75% of known models. This is a big step towards uncovering the one neutron star ‘equation of state’ […]

Scientists spot hidden companions of bright stars

Photographing faint objects close to bright stars is incredibly difficult. Yet, by combining data from ESA’s Gaia space telescope with ESO’s GRAVITY instrument on the ground, scientists managed just that. They took the first pictures of so far unseen dim companions of eight luminous stars. The technique unlocks the tantalising possibility to capture images of […]
