The moon is still looking big and bright in the sky after last night’s full moon, so what can we see? Keep reading to find out what’s going on with the lunar phase now. The lunar phase is a series of eight unique phases of the moon’s visibility. The whole cycle takes about 29.5 days, according to NASA, and these …

A group of Chinese scientists has overcome a challenge that stumped biologists for decades by developing a new gene-editing tool that can precisely manipulate millions of base pairs – the building blocks of DNA. The innovation has been hailed as “very significant progress” by Professor Yin Hao, a gene editing specialist at Wuhan University’s medical research institute, who was not …

‘Cosmic tunnel’: Scientists confirm presence of a mysterious doorway linking our solar system to distant constellations  WION Source link

As a child, I remember gazing up at the stars and dreaming of spacecraft journeying to distant worlds, those classic images of rockets blasting off toward unknown frontiers filled my imagination. But a mission to a black hole? That seemed beyond even the wildest science fiction. These stellar corpses were the stuff of theoretical physics books back then, mysterious objects …

Press enter or click to view image in full size (Image credit: Max Barry/Nation States) A simple way to distinguish a spacecraft from a rock is through its large non-gravitational acceleration. A natural icy rock like a comet is propelled by its mass loss. That mass loss can be observed through the cometary plume of gas and dust that surrounds …

Key numbers used Voyager 1 speed ≈ 17 km/s (typical quoted value). 1 astronomical unit (AU) = 149,597,870.7 km. 1 year ≈ 365.25 days and 1 day = 86,400 seconds. Convert Voyager speed to AU per year (digit-by-digit) Seconds per year = 86,400 × 365.25 = 31,557,600 s. Distance per year = 17 km/s × 31,557,600 s = 536,479,200 km/year. …

Communication depends on Voyager’s 3.7-metre high-gain antenna transmitting narrow, low-power X-band radio signals. Those signals are captured by NASA’s Deep Space Network, three arrays of huge dishes in California, Spain and Australia, which amplify and decode the faint transmissions. The probe transmits slowly and in short bursts, storing data onboard and sending it in low-rate streams that the DSN reconstructs …
