Super Luminous Supernova (SLSNe)
Relevance IN - Prelims ( about SLSNe + about Supernova + TELESCOPES used in studying it )
What's the NEWS
- An extremely bright, hydrogen deficient, fast-evolving supernova that shines with the energy borrowed from an exotic type of neutron star with an ultra-powerful magnetic field has been spotted by Indian researchers.
- Deep study of such ancient spatial objects can help probe the mysteries of the early universe.
Know! about SLSNe
- Such type of supernovae called Super Luminous Supernova (SLSNe) is very rare.
- This is because they are generally originated from very massive stars (minimum mass limit is more than 25 times to that of the Sun), and the number distribution of such massive stars in our galaxy or in nearby galaxies is sparse.
- Among them, SLSNe-I has been counted to about 150 entities spectroscopically confirmed so far.
- These ancient objects are among the least understood SNe because their underlying sources are unclear
- SN 2020ank, which was first discovered by the Zwicky Transient Facility on 2020 January 19, was studied by scientists from Aryabhatta Research Institute of Observational Sciences (ARIES) Nainital, an autonomous research institute under the Department of Science and Technology (DST) Govt. of India
- The team observed it using special arrangements at India's recently commissioned Devasthal Optical Telescope (DOT-3.6m) along with two other Indian telescopes: Sampurnanand Telescope-1.04m and Himalayan Chandra Telescope-2.0m.
- They found that the outer layers of the onion structured Supernovae had been peeled off, and the core was shining with a borrowed energy source.
Devasthal Optical Telescope (DOT-3.6m) Sampurnanand Telescope-1.04m and Himalayan Chandra Telescope-2.0m.
- The 3.6m Devasthal Optical Telescope is a clear-aperture Ritchey-Chrétien telescope built by Aryabhatta Research Institute of Observational Sciences and is located at the Devasthal Observatory site near Nainital, Uttarakhand,
- The 104-cm Sampurnanand Telescope, located at ARIES, Manora Peak, Nainital , is one of the main observing facility in optical domain.
- The Himalayan Chandra Telescope is located at the Indian Astronomical Observatory (IAO) at Hanle, Ladakh.
Know! about Supernova
- A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star.
- One type of supernova is caused by the "last hurrah" of a dying massive star. This happens when a star at least five times the mass of our sun goes out with a fantastic bang!
- Massive stars burn huge amounts of nuclear fuel at their cores, or centers. This produces tons of energy, so the center gets very hot. Heat generates pressure, and the pressure created by a star's nuclear burning also keeps that star from collapsing.
- A star is in balance between two opposite forces. The star's gravity tries to squeeze the star into the smallest, tightest ball possible. But the nuclear fuel burning in the star's core creates strong outward pressure. This outward push resists the inward squeeze of gravity.
- The balance of gravity pushing in on the star and heat and pressure pushing outward from the star's core holds the stars together
- When a massive star runs out of fuel, it cools off. This causes the pressure to drop. Gravity wins out, and the star suddenly collapses.
- The collapse happens so quickly that it creates enormous shock waves that cause the outer part of the star to explode!
- Usually a very dense core is left behind, along with an expanding cloud of hot gas called a nebula.
- A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe-black holes.
- The Crab Nebula is the leftover, or remnant, of a massive star in our Milky Way that died 6,500 light-years away. Astronomers and careful observers saw the supernova in the year 1054.
- A second type of supernova can happen in systems where two stars orbit one another and at least one of those stars is an Earth-sized white dwarf.
- A white dwarf is what's left after a star the size of our sun has run out of fuel. If one white dwarf collides with another or pulls too much matter from its nearby star, the white dwarf can explode.

First Private LNG Facility plant launched
Relevance IN - Prelims ( about LNG + about flex engines)
What's the NEWS
- Inaugurating the country's first private LNG facility plant at Nagpur Minister for Road Transport and Highways emphasised the importance of alternate biofuels for diversification of agriculture towards the energy and power sector.
- India is spending eight lakh crores for the import of petrol, diesel and petroleum products which is a big challenge.
- The government has designed a policy that encourages development of imports to substitute cost effective pollution free and indigenous ethanol, bio CNG, LNG and hydrogen fuels.
- The ministry is constantly working on different alternative fuels. We must use surplus rice, corn and sugar to prevent it from going to waste
About flex engines
- A decision would be taken in three months, making it mandatory for automobile manufacturers, particularly the four-wheelers and two-wheelers, to make flex engines.
- Countries like the USA, Canada and Brazil already have them and the cost of the vehicle remains the same whether it is petrol or flex engine.
- A flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank.
- Modern flex-fuel engines are capable of burning any proportion of the resulting blend in the combustion chamber as fuel injection and spark timing are adjusted automatically according to the actual blend detected by a fuel composition sensor.
- Flex-fuel vehicles are distinguished from bi-fuel vehicles, where two fuels are stored in separate tanks and the engine runs on one fuel at a time, for example, compressed natural gas (CNG), liquefied petroleum gas (LPG), or hydrogen.
Liquefied natural gas (LNG)
- It is the liquefied form of natural gas, which has a much smaller volume than natural gas in its gaseous form. This liquefied condition is used to facilitate the carriage of natural gas over long distances, often by sea, in specialized tanks.
- LNG port terminals are purpose-built port terminals designed to accommodate large LNG carrier ships designed to load, carry and unload LNG.
- These LNG terminals are located adjacent to a gas liquefaction and storage plant (export), or to a gas regasification and storage plant (import), which are themselves connected to gas pipelines connected to on-shore or off-shore gas fields (export) or to storage and distribution plants (import).
