Hobby-Eberly Telescope Dark Energy Experiment ( HETDEX )

"  Astronomers Create the Largest 3D Map of the Early Universe’s Hydrogen Glow " - Gadgets360 The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is a major spectroscopic survey at McDonald Observatory aimed at understanding dark energy—the force accelerating the universe's expansion. Using the 10-meter Hobby-Eberly Telescope (HET) and VIRUS spectrographs, it maps over one million galaxies 9–11 billion light-years away.  HETDEX is currently collecting data on at least one million galaxies that are 9 billion to 11 billion light-years away, yielding the largest map of the early universe ever produced.  Key Details of HETDEX: Goal: To measure the expansion rate of the universe and determine if dark energy changes over time by mapping the 3D positions of over a million distant galaxies (specifically, Lyman-alpha emitters). Instrument: The survey uses VIRUS (Visible Integral-Field Replicable Unit Spectrograph), which consists of 150 spectrographs connected by 33,000+ op...

Government announces standards of Green Ammonia and Green Methanol for India to accelerate trade of Green Hydrogen derivatives

In a significant move for the advancement of the   National Green Hydrogen Mission , the Government of India notified the Green Ammonia and Green Methanol Standards for India on 27 th   February 2026. The standards issued by the Ministry of New and Renewable Energy (MNRE), outlines the emission thresholds and eligibility conditions that must be compiled in order for ammonia & methanol produced to be classified as ‘Green’, i.e., produced using Green Hydrogen derived from renewable sources. Green Ammonia Standard for India -  Green Ammonia shall have a  total non-biogenic greenhouse gas emission , arising from Green Hydrogen production, ammonia synthesis, purification, compression, and on-site storage, of  not more than 0.38 kg CO₂ equivalent per kg of ammonia (kg CO₂ eq/kg NH₃) , calculated as an average over the preceding 12-month period. Green Methanol standard for India -  Green Methanol shall have a  total non-biogenic greenhouse gas emission , ...

Common Leopard

Key Facts Common Name: Indian leopard or common leopard Scientific Name: Panthera pardus Population: No official countrywide population estimate is available. However, within the 17 tiger bearing states of India, the leopard occupies an area of around 1,74,066 km2, nearly double the area occupied by the tiger Height: 45-80 cms Length: Head-body length: 100-190 cm, Tail length: 70-95 cm Weight: Male: 30-70 kg, Female: 28-60 kg Status: Listed in Schedule I of the Indian Wildlife (Protection) Act, 1972 and included in Appendix I of CITES. Listed as Near Threatened on the IUCN Red List Characteristics Nine subspecies of the leopard have been recognized, and they are distributed across Africa and Asia. Each of them vary to some degree in appearance and biology as one moves across this wide geographical range, but their exceptionally beautiful black-spotted coat, supreme stealth, and elusive nature remains common. The leopard is the smallest of the big cats, and known for its ability to adap...

Megamaser

An  astrophysical maser  is a naturally occurring source of  stimulated   spectral line  emission, typically in the  microwave  portion of the  electromagnetic spectrum . This emission may arise in  molecular clouds ,  comets ,  planetary   atmospheres ,  stellar atmospheres , or various other conditions in  interstellar space . This galaxy has a far more exciting and futuristic classification than most — it hosts a megamaser. Megamasers are intensely bright, around 100 million times brighter than the masers found in galaxies like the Milky Way. The entire galaxy essentially acts as an astronomical laser that beams out microwave emission rather than visible light (hence the ‘m’ replacing the ‘l’). A megamaser is a process where some components within a galaxy (like gas clouds) are in the right stimulated physical condition to radiate intense energy (in this case, microwaves).
