More specifically, the diffractive pupil mirror pattern spreads starlight into a complex flower pattern. This makes it easier to show the fine detail needed to detect the small wobbles a planet would make in the star’s motion.

TOLIMAN fills an important niche in the study of exoplanets, searching for them around the very nearest stars. As has been noted, that task has actually been more difficult, so far, than finding planets around more distant stars. TOLIMAN will focus on detecting these worlds, if they are there. What will it find?

Bottom line: A new custom-designed space telescope mission called TOLIMAN will search for nearby habitable planets in the closest star system to Earth, Alpha Centauri.

The hunt is on for leptoquarks, particles beyond the limits of the standard model of particle physics —the best description we have so far of the physics that governs the forces of the Universe and its particles. These hypothetical particles could prove useful in explaining experimental and theoretical anomalies observed at particle accelerators such as the Large Hadron Collider (LHC) and could help to unify theories of physics beyond the standard model, if researchers could just spot them.

A new paper published in Nuclear Physics B by Anirban Karan, Priyotosh Bandyopadhyay, and Saunak Dutta, of the Indian Institute of Technology Hyderabad, Kandi, together with Mahesh Jakkapu, Graduate University for Advanced Studies (SOKENDAI), Kanagawa, Japan, examines the potential signatures of leptoquarks at the LHC to see how they could arise from proton-proton collisions for the possible mass ranges of these particles.

The main objective of this research is how to distinguish the signatures of different leptoquarks at proton-proton colliders like LHC or its proposed successor, Karan says.

The possibility of space mining in future was thrown into sharp relief this weekend as a Near Earth Asteroid (NEA) called 4,660 Nereus passed our planet.

Worth an estimated $5 billion in precious metals and measuring 330 meters across, Nereus at no point came anywhere near being dangerous, getting no closer than 2.4 million miles/3.9 million kilometers at 13:51 UTC on Saturday, December 11, 2021.

That’s about 10 times the distance between the Earth and the Moon.

NASA is about to launch the world’s most powerful space telescope. Webb’s first year of science could rewrite the history of the universe.

Recently, OpenAI opened public access to GPT-3, one of the world’s most sophisticated AI writing tools. It might fool you in a conversation.

While all atomic nuclei except hydrogen are composed of protons and neutrons, physicists have been searching for a particle consisting of two, three or four neutrons for over half a century. Experiments by a team of physicists of the Technical University of Munich (TUM) at the accelerator laboratory on the Garching research campus now indicate that a particle comprising four bound neutrons may well exist.

While nuclear physicists agree that there are no systems in the universe made of only protons, they have been searching for particles comprising two, three or four neutrons for more than 50 years.

Should such a particle exist, parts of the theory of the strong interaction would need to be rethought. In addition, studying these particles in more detail could help us better understand the properties of neutron stars.
