Mega-constellations, rockets and supersonic aircraft could thwart ozone layer's recovery
The Earth's protective ozone layer is recovering thanks to the successful implementation of the Montreal Protocol. But new threats are emerging that might set back the efforts, scientists say.
Webb’s view of the molecular cloud Chameleon I
Video: 00:00:30
This video features a new image from the NASA/ESA/CSA James Webb Space Telescope’s Near-InfraRed Camera (NIRCam), showcasing the low-mass star forming region Chameleon I.
An international team of astronomers has reported the discovery of diverse ices in the darkest, coldest regions of a molecular cloud measured to date by studying this region. This result allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets, while opening a new window on the origin of more complex molecules that are the first step in the creation of the building blocks of life.
This research forms part of the Ice Age project, one of Webb's 13 Early Release Science programs, which has studied a dust ridge in the centre of the Chameleon I molecular cloud.

Webb unveils dark side of pre-stellar ice chemistry
The discovery of diverse ices in the darkest, coldest regions of a molecular cloud measured to date has been announced by an international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope. This result allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets, while opening a new window on the origin of more complex molecules that are the first step in the creation of the building blocks of life.

ESA to help develop secure quantum communications
Staying safe from cyberattacks that target vital services such as power supplies is increasingly important in today’s digital world. ESA is supporting European autonomy to keep people connected by working with satellite manufacturer Thales Alenia Space to develop highly secure technologies based on the unbreakable laws of quantum physics.
Titan’s Dragonfly Test, New Nuclear Rocket, Shadow Universe
The Titan Dragonfly is coming together, NASA is considering a new kind of nuclear rocket, getting more warning for solar flares, and pinpointing carbon emissions from space.
Titan Helicopter Starts to Come Together
A nuclear-powered helicopter called Dragonfly is coming to Titan soon. The mission is planned for launch in 2027, so we’re starting to see it come together. NASA performed a test of an arm with rotors in its wind tunnel. They were able to mimic the conditions on titan and see how the helicopter’s rotors would behave. It’s one of the first stages of testing, so as the launch date approaches, we will see more parts of Dragonfly coming together.
Mars In 45 Days
NASA has developed two kinds of nuclear-powered propulsion systems. One is nuclear thermal propulsion, where a nuclear reactor heats a propellant and blasts out the rocket nozzle. The other method uses a nuclear reactor to generate electricity to power an ion engine. A new NIAC grant proposes merging these two ideas into a single “bimodal nuclear thermal rocket.” Once constructed, a rocket like this could shorten the flight time to Mars from months to just 45 days.
