Feeling the heat from space
With searing temperatures and a string of record highs being smashed across western Europe, the current heatwave is all too apparent. Extreme heat warnings have been issued in several countries including France, Spain and Portugal, and deadly wildfires have forced thousands to flee their homes. The satellite images here are an example of how the crisis is being viewed by satellites orbiting Earth.
First spacewalk for Samantha Cristoforetti
On 21 July 2022, ESA astronaut Samantha Cristoforetti will head outside the International Space Station on a spacewalk alongside cosmonaut Oleg Artemyev. It will be Samantha’s first spacewalk, and the first conducted by a European woman.
Mars Express peers into Mars' 'Grand Canyon'
The latest image release from ESA’s Mars Express takes us over two ruptures in the martian crust that form part of the mighty Valles Marineris canyon system.
We Finally Know Where the Highest Energy Cosmic Rays are Coming From: Blazars
Way out there in space is a class of objects called blazars. Think of them as extreme particle accelerators, able to marshall energies a million times stronger than the Large Hadron Collider in Switzerland. It turns out they’re the culprits in one of the great astrophysical mysteries: what creates and propels neutrinos across the universe at blazingly fast speeds? It turns out that the answer’s been there all along: blazars pump out neutrinos and cosmic rays. That’s the conclusion a group of astronomers led by Dr. Sara Buson of Universität Wurzburg in Germany came to as they studied data from a very unique facility here on Earth: the IceCube Neutrino Observatory in Antarctica.
The Gravitational Constant is Tricky to pin Down Accurately. Here’s a new way to Measure it
A team of physicists have used a pair of vibrating rods to measure the gravitational constant to incredibly fine precision. While the new technique has relatively high uncertainty, they hope that future improvements will provide a new pathway to nailing down this elusive constant.

We’ll be Building Self-Replicating Probes to Explore the Milky Way Sooner Than you Think. Why Haven’t ETIs?
The future can arrive in sudden bursts. What seems a long way off can suddenly jump into view, especially when technology is involved. That might be true of self-replicating machines. Will we combine 3D printing with in-situ resource utilization to build self-replicating space probes?
