In physics and mechanics, torque is the rotational analogue of linear force. It is also referred to as the moment of force (also abbreviated to moment). It describes the rate of change of angular momentum that would be imparted to an isolated body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "Give me a lever and a place to stand and I will move the Earth". Just as a linear force is a push or a pull applied to a body, a torque can be thought of as a twist applied to an object with respect to a chosen point. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque.

Hubble Observes Galaxy ESO 174-1
◉ The highly irregular galaxy ESO 174-1, which resembles a lonely, hazy cloud against a backdrop of bright stars, dominates this image from the NASA/ESA Hubble Space Telescope. ESO 174-1 lies around 11 million light-years from Earth and consists of a bright cloud of stars and a faint, meandering tendril of dark gas and dust. This image is part of a collection of Hubble observations designed to better understand our nearby galactic neighbors.
◉ The observations aim to resolve the brightest stars and basic properties of every known galaxy within 10 megaparsecs.
▸A parsec is a unit used by astronomers to measure the vast distances to other galaxies – 10 megaparsecs translates to 32 million light-years – and makes astronomical distances easier to handle. For example, the nearest star to the Sun, Proxima Centauri, is about 1.3 parsecs away. In everyday units this is a staggering 25 trillion miles (40 trillion km)!

Roscosmos has confirmed that it's Luna 25 moon mission has failed. It happened due to an engine failure due to which the engines that were supposed to lead Luna 25 to the pre-landing orbit didn't shut down in time and worked for 127 seconds instead of the planned 84 seconds.
Now, all eyes are lying on India's Chandrayaan , which is expected to make a landing on 23rd August 2023 at around 6:04 p.m. IST.

The Japanese Aerospace Exploration Agency (JAXA) said the homegrown H-IIA rocket took off from Tanegashima Space Center in southern Japan on 7th september 2023 and successfully released the Smart Lander for Investigating Moon (SLIM).
Dubbed the “Moon Sniper”, JAXA aims to land SLIM within 100 metres (328 feet) of its target site on the lunar surface. The $100m mission is expected to reach the moon by February next year.

🛰️ "Hubble" has entered safe mode due to gyroscope issues
The Hubble Space Telescope entered safe mode on November 23, 2023, suspending scientific observations for an indefinite period. It initially entered safe mode on November 19 due to issues with one of its gyroscopes, which are responsible for orienting the observatory.
