What is it like to work on the fundamental questions about the universe? On July 1, the Euclid satellite launched successfully. This mission from the European Space Agency will take images of the sky to create the most detailed map of the universe ever made. Astronomer Henk Hoekstra (Leiden Observatory) and physicist Alessandra Silvestri (Leiden Institute of Physics) tell about their role in the mission.
The new space satellite is like the Google of the universe. "Euclid is basically a data-gathering machine," Hoekstra explains. "What Hubble covered in 30 years, Euclid can do in one week in both optical and infrared wavelengths. So it's a huge volume of data. With this, you are guaranteed to find the needle in a haystack."
Hoekstra has multiple roles in the mission. He is the lead of the weak lensing group and one of the four cosmology coordinators. This means he was involved from the early stages to set the requirements for the accuracy of the data Euclid will obtain.

The Aerospace Information Research Institute (AIR) under the Chinese Academy of Sciences (CAS), in partnership with the Changguang Satellite Technology, successfully conducted a satellite-to-ground laser communication experiment at a speed of 10 gigabyte per second (GB/s) using self-developed 500-millimeter-diameter ground system and Jilin-1 satellite.
The experiment obtained good-quality Earth formed from dry, rocky building blocks

Billions of years ago, in the giant disk of dust, gas, and rocky material that orbited our young sun, larger and larger bodies coalesced to eventually give rise to the planets, moons, and asteroids we see today. Scientists are still trying to understand the processes by which planets, including our home planet, were formed. One way researchers can study how Earth formed is to examine the magmas Satellogic and OHB to collaborate on environmental earth observation applications

Elucidating the atmosphere and surface environment of the early Earth, especially before the origin of life, is a key to understanding the habitability of the Earth. The atmosphere of terrestrial planets has been thought to be formed by degassing volatiles from the interior and its composition is mainly controlled by the oxidation state of the mantle. To understand the mantle oxidation state, th Superconducting qubit foundry accelerates progress in quantum research

In the past three decades, quantum computing has grown from a theoretical fantasy to a worldwide industry, pushing closer to a technology that could one day solve problems too complex for even the most powerful supercomputers. MIT Lincoln Laboratory is not only at the forefront of research, but is making quantum research accessible to a broader community through its Superconducting Qubits at Lin 'Sandwich' discovery offers new explanation for planet formation

Scientists have made a new discovery on how small planets might form.
Researchers at the University of Warwick investigated the "birth environment" of planets - areas of gas and dust that swirl around a central star - known as the protoplanetary disc.
They discovered a new method of planet formation in this region, not yet described in previous research. The work has been submitted t PIGS finds ancient stars in the heart of the Milky Way

An international team of researchers has obtained the largest set of detailed observations yet of the oldest stars in the centre of our Galaxy, the Milky Way. The Pristine Inner Galaxy Survey (PIGS) team finds that this group of stars is slowly spinning around the centre of the Milky Way, despite being thought to have formed in a chaotic fashion.
