India’s first solar mission, Aditya L1, has exited the Earth’s orbit and is heading towards the sun to study its secrets.
India’s first solar mission, Aditya L1, has crossed a major milestone in its journey to explore the mysteries of the Sun. The Indian Space Research Organisation (ISRO) announced on Saturday that the spacecraft has exited the Earth’s sphere of influence, which is the region where the Earth’s gravity dominates over other celestial bodies. This is only the second time that ISRO has achieved this feat, the first being the Mars Orbiter Mission in 2013.

Researchers at the Indian Institute of Science (IISc) have developed a fully indigenous gallium nitride (GaN) power switch that can have potential applications in systems like power converters for electric vehicles and laptops, as well as in wireless communications. The entire process of building the switch—from material growth to device fabrication to packaging—was developed in-house at the Center for Nano Science and Engineering (CeNSE), IISc.
Due to their high performance and efficiency, GaN transistors are poised to replace traditional silicon-based transistors as the building blocks in many electronic devices, such as ultrafast chargers for electric vehicles, phones and laptops, as well as space and military applications such as radar.
“It is a very promising and disruptive technology,” says Digbijoy Nath, Associate Professor at CeNSE and corresponding author of the study published in Microelectronic Engineering. “But the material and devices are heavily import-restricted … We don’t have gallium nitride wafer production capability at commercial scale in India yet.” The know-how of manufacturing these devices is also a heavily-guarded secret with few studies published on the details of the processes involved, he adds.

Back in 2018, a tank of the purest water, buried under kilometers of rock in Ontario, Canada, flashed as barely detectable particle slammed through its molecules.
It was the first time that water has been used to detect a particle known as an antineutrino, which originated from a nuclear reactor more than 240 kilometers (150 miles) away. This incredible breakthrough promises neutrino experiments and monitoring technology that use inexpensive, easily acquirable and safe materials.
As some of the most abundant particles in the Universe, neutrinos are odd little things with a lot of potential for revealing deeper insights into the Universe. Unfortunately they are almost massless, carry no charge, and barely interact with other particles at all. They mostly stream through space and rock alike, as though all matter was incorporeal. There’s a reason they’re known as ghost particles.
The initial discovery of the alignment of planetary nebulae was made a decade ago by Bryan Rees, a Manchester PhD student, but has remained unexplained.

India’s sun-monitoring spacecraft has crossed a landmark point on its journey to escape “the sphere of Earth’s influence”, its space agency said, days after the disappointment of its moon rover failing to awaken.
The Aditya-L1 mission, which started its four-month journey towards the center of the solar system on September 2, carries instruments to observe the sun’s outermost layers.
“The spacecraft has escaped the sphere of Earth’s influence,” the Indian Space Research Organisation (ISRO) said in a statement late Saturday.
NASA has officially called upon companies to submit designs for a so-called U.S. Deorbit Vehicle (USDV) for the International Space Station (ISS). This pioneering spacecraft would have the crucial mission of safely bringing the ISS back to Earth, marking the ISS’s planned retirement.
The unprecedented project comes with an estimated price tag “a little short of about $1 billion,” as reported earlier this year by Kathy Lueders, NASA Associate Administrator for Space Operations.
Although initial considerations revolved around employing Russian spaceships for this monumental task, NASA, in a strategic shift, opened the floor this month to proposals from U.S. industry. The deadline for these innovative submissions is set for November 17, following the initiation of the call for designs on September 20.
A strange pair of galaxies several billion light-years away could be evidence of a hypothetical ‘crease’ in the Universe’s fabric known as a cosmic string.
According to an analysis of the properties of the pair, the two galaxies may not be distinct objects, but a duplicate image caused by a trick of the light. And the reason the light is duplicated could be because of a scar in the space between us and the galaxy, creating a gravitational lens.
A paper describing this cosmic string candidate, led by Margarita Safonova of the Indian Institute of Astrophysics, has been accepted in the Bulletin de la Société Royale des Sciences de Liège, and is available on preprint server arXiv.
The instrumental title track “I Robot”, together with the successful single “I Wouldn’t Want To Be Like You”, form the opening of “I Robot”, a progressive rock album recorded by The Alan Parsons Project and engineered by Alan Parsons and Eric Woolfson in 1977. It was released by Arista Records in 1977 and re-released on CD in 1984 and 2007. It was intended to be based on the “I, Robot” stories written by Isaac Asimov, and actually Woolfson spoke with Asimov, who was enthusiastic about the concept. However, as the rights had already been granted to a TV/movie company, the album’s title was altered slightly by removing the comma, and the theme and lyrics were made to be more generically about robots rather than specific to the Asimov universe. The cover inlay reads: “I ROBOT… HE STORY OF THE RISE OF THE MACHINE AND THE DECLINE OF MAN, WHICH PARADOXICALLY COINCIDED WITH HIS DISCOVERY OF THE WHEEL… ND A WARNING THAT HIS BRIEF DOMINANCE OF THIS PLANET WILL PROBABLY END, BECAUSE MAN TRIED TO CREATE ROBOT IN HIS OWN IMAGE.” The Alan Parsons Project were a British progressive rock band, active between 1975 and 1990, founded by Eric Woolfson and Alan Parsons. Englishman Alan Parsons (born 20 December 1948) met Scotsman Eric Norman Woolfson (18 March 1945 — 2 December 2009) in the canteen of Abbey Road Studios in the summer of 1974. Parsons had already acted as assistant engineer on The Beatles’ “Abbey Road” and “Let It Be”, had recently engineered Pink Floyd’s “The Dark Side Of The Moon”, and had produced several acts for EMI Records. Woolfson, a songwriter and composer, was working as a session pianist, and he had also composed material for a concept album idea based on the work of Edgar Allan Poe. Parsons asked Woolfson to become his manager and Woolfson managed Parsons’ career as a producer and engineer through a string of successes including Pilot, Steve Harley, Cockney Rebel, John Miles, Al Stewart, Ambrosia and The Hollies. Parsons commented at the time that he felt frustrated in having to accommodate the views of some of the musicians, which he felt interfered with his production. Woolfson came up with the idea of making an album based on developments in the film industry, where directors such as Alfred Hitchcock and Stanley Kubrick were the focal point of the film’s promotion, rather than individual film stars. If the film industry was becoming a director’s medium, Woolfson felt the music business might well become a producer’s medium. Recalling his earlier Edgar Allan Poe material, Woolfson saw a way to combine his and Parsons’ respective talents. Parsons would produce and engineer songs written by the two, and The Alan Parsons Project was born.
