NASA writes: On Aug. 5, 2011, NASA’s Juno spacecraft launched on a five-year interplanetary journey that took it to the giant planet Jupiter. NASA’s Jet Propulsion Laboratory in Pasadena, California, manages the Juno mission and its operations. The goal of the spacecraft was to enter orbit around the planet and use its suite of scientific instruments and cameras to observe Jupiter’s atmosphere, gravity and magnetic fields. The understanding of the planet’s properties can reveal clues about its origins and evolution. Juno arrived at Jupiter in July 2016 and entered an elliptical polar orbit around the planet. It continues its observations of the largest planet in our solar system, returning spectacular images of the gas giant, even to this day.

NASA writes: Ask any space explorer, and they’ll have a favorite photo or two from their mission. For Kevin Hand, a scientist at NASA’s Jet Propulsion Laboratory in Southern California and co-lead of the Perseverance rover’s first science campaign, his latest favorite is a 3D image of low-lying wrinkles in the surface of Jezero Crater. The science team calls this area “Raised Ridges.” NASA’s Ingenuity Mars Helicopter captured the two shots for this stereo image on July 24 during its 10th flight.
NASA writes: You’d think that supernovae – the death throes of massive stars and among the brightest, most powerful explosions in the universe – would be hard to miss. Yet the number of these blasts observed in the distant parts of the universe falls way short of astrophysicists’ predictions. A new study using data from NASA’s recently retired Spitzer Space Telescope reports the detection of five supernovae that, going undetected in optical light, had never been seen before. Spitzer saw the universe in infrared light, which pierces through dust clouds that block optical light – the kind of light our eyes see and that unobscured supernovae radiate most brightly.
writes: India’s ruling party, the Bharatiya Janata Party (BJP), is sometimes said to prioritize Hindu interests. Hindus were the religious group most likely to say they voted for the BJP in the country’s most recent parliamentary election, but there are vast differences in how Hindus from different regions voted, according to a recent Pew Research Center survey of nearly 30,000 Indian adults. These regional political differences are connected to Hindu attitudes on a range of issues including language, diet and religious observance.

writes: Gun owners in the United States have long favored more permissive gun policies while adults who do not own guns have tended to favor more restrictive policies. This pattern continues today. For example, 37% of gun owners favor banning assault-style weapons, compared with twice as many (74%) non-gun owners – and this gap has grown in recent years, according to a new analysis of Pew Research Center surveys conducted in April and June 2021.

Valeria Guarnieri writes: Anche i buchi neri hanno il loro ‘Signore degli Anelli’: nel sistema V404 Cygni, infatti, è stato scovato uno di questi elusivi oggetti celesti, insolitamente attorniato da una serie di strutture concentriche. A fare la scoperta, nell’estate del 2015, è stata una coppia di osservatori spaziali della Nasa, Chandra e Neil Gehrels Swift. Il particolare buco nero, protagonista all’epoca di uno studio su The Astrophysical Journal, torna alla ribalta per una nuova immagine che, oltre ai dati di Chandra nei raggi X, contiene quelli nell’ottico del telescopio Pan-Starrs, situato alle Hawaii

KM Seethi writes: The Arctic has recently assumed considerable strategic significance as it has been underlined by the policies of major powers. The interests and concerns of the Arctic states are vast and varied. India, being an observer in the Arctic Council, has legitimate interests in the region and has created its own Arctic policy. India’s Arctic policy, notified as a draft document in early January 2021, continues along the lines of the country’s science diplomacy
