Hubble Space Telescope captures jellyfish galaxy JO201
- It is a jellyfish galaxy which lies in Abell 85 galaxy cluster.
- It is at a distance of about 700 million lightyears, in the constellation of Cetus or the Whale.
Jellyfish galaxies
- They are a type of galaxy that exhibit long “tentacles” or “tails” of gas, dust, and stars that appear to be streaming away from the galaxy’s main body.
- These tentacles are formed as the galaxy moves rapidly through the hot gas of a galaxy cluster, causing the gas to strip away from the galaxy and form a tail. This process is called ram-pressure stripping.
- The tendrils of jellyfish galaxies extend beyond the bright disc of the galaxy''s core.
Galaxy clusters
- They are the largest objects in the universe that are held together by their own gravity.
- They contain hundreds or thousands of galaxies, lots of hot plasma, and a large amount of invisible dark matter.
- Galaxy clusters are home to the biggest galaxies in the known universe and provide us with information about the structure of the universe on the largest scales.

First Look at Ryugu Asteroid Sample Reveals it is Organic-Rich
- It is a Japanese spacecraft that studied the asteroid Ryugu, collected samples, and brought them to Earth for analysis.
- It was the first to deploy rovers to operate on an asteroid.
- Mission Objectives:
- To clarify the origin and evolution of the Solar System, including the beginnings of life.
- To establish deep space exploration technology by taking on new challenges.
- It was launched by the Japan Aerospace Exploration Agency (JAXA) in December 2014.
- It arrived at asteroid Ryugu on June 2018, collected samples from the asteroid during two touchdowns in 2019, and delivered the sample capsule back to the Earth on December 2020.
- After delivering the capsule, the spacecraft continued on to a new mission. This new phase is referred to as the “Extended Mission”, with a new target destination of the small asteroid, 1998 KY26.
- Hayabusa2 is a follow-up to Japan’s original Hayabusa mission, which was the first spacecraft to take samples from an asteroid, and was also the first mission to successfully land and take off from an asteroid. It returned samples from asteroid 25143 Itokawa to Earth on June 13, 2010.
Astronomers discover ‘Elusive Dying Radio Galaxies’ using deep radio surveys
- Radio Galaxies, also known as radio-luminous galaxies or radio-loud galaxies, are a particular type of active galaxy that emits more light at radio wavelengths than at visible wavelengths.
- These happen through the interaction between charged particles and strong magnetic fields related to supermassive black holes at the galaxies’ center.
- Radio galaxies are driven by non-thermal emissions.
- They are much bigger than most of the other galaxies in the universe.
- There are two broad classes of radio galaxies:
- Core-halo radio galaxies:
- They exhibit radio emission from a region concentrated around the nucleus of the galaxy.
- The region of radio emission is comparable in size to the optically visible galaxy.
- Lobed radio galaxies:
- They display great lobes of radio emission extending, in some cases, for millions of light years beyond the optical part of the galaxy.
- Some radio galaxies have a single lobe, but more often, the lobes are double, arrayed on both sides of the optical galaxy.
Japan to buy 400 Tomahawk missiles from US: PM Fumio Kishida
- It is an American-made long-range cruise missile used for deep land attack warfare.
- It can be launched from a ship or submarine and can deliver its warhead precisely to a target at a long range.
- They are designed to fly at extremely low altitudes at high subsonic speeds.
- It has an accuracy of about 5 meters (16 feet).
- The 6-meter (18.4-foot-) long missile has a range of up to 2,400 km (1,500 miles) and can travel as fast as 885 km (550 miles) per hour.
- The missile is powered by a solid propellant during its launch phase. Thereafter it is powered by a turbofan enginethat does not emit much heat, which makes infrared detection difficult.
- It is capable of twisting and turning like a radar-evading fighter plane.
- There are several variants of the Tomahawk missile, each with specialized capabilities.
Italian PM Giorgia Meloni to be chief guest at 8th Raisina Dialogue, says MEA
- It is India’s premier conference on geopolitics and geoeconomics, committed to addressing the most challenging issues facing the global community.

- It is organized by the Observer Research Foundation (ORF) in partnership with the Ministry of External Affairs, Government of India.
Observer Research Foundation (ORF):
- Established in 1990, the ORF is an independent, nonpartisan think tank that conducts policy research on good governance, foreign policy, and sustainable economic development for India.
- ORF’s work spans a wide range of topics, including climate, energy, cyber issues and media, economic development, and national security.
- It provides non-partisan, independent, well-researched analyses and inputs to diverse decision-makers in governments, business communities, academia, and to civil society around the world.

Augmented reality headset enables users to see hidden objects
- It is an enhanced version of the real physical world that is achieved through the use of digital visual elements, sound, or other sensory stimuli and delivered via technology.
- It overlays digital content onto real-life environments and objects.
- AR works by superimposing digital information onto real-world objects to create a 3D experience that allows users to interact with both the physical and digital worlds.
- It incorporates three features: a combination of digital and physical worlds, interactions made in real time, and accurate 3D identification of virtual and real objects.
- Unlike Virtual Reality (VR), which creates its own cyber environment, AR adds to the existing world as it is.
Virtual Reality (VR)
- It is a simulated 3D environment that enables users to explore and interact with a virtual surrounding in a way that approximates reality as it is perceived through the users'' senses.
- The environment is created with computer hardware and software, and the users need to wear devices such as helmets or goggles (Virtual Reality headsets or helmets) to interact with the environment.
