As sun blinks from amid clouds, scientists witness Zero Shadow Day

As young space enthusiasts gathered at the Indian Institute of Astrophysics (IIAP) here on Friday to witness the Zero Shadow Day', they feared that the cloudy skies would cast a shadow on the rare celestial event. Zero Shadow Day or No Shadow Day is a phenomenon during which the sun is positioned directly overhead causing no shadows to be formed on the earth's surface. However, the clouds provided a 45-second window for the sun to blink at the nick of the moment before hiding, much to the delight of students and the scientific community. The IIAP, Bengaluru had organised the event on its premises in Koramangala this afternoon. A large number of students had gathered to have a glimpse of Zero Shadow Day', which occurred exactly at 12:20 pm in the city. For the past few days sun was shining bright but on Friday dark clouds hovered over the sky, threatening to mar the rare phenomenon. Yet, with hopes that the phenomenon would occur, the scientific community made all the arrangements.

Breakthrough in fusion harnessing could be climate, energy game-changer

Energy Secretary Jennifer Granholm announced a major scientific breakthrough Tuesday in the decades-long quest to harness fusion, the energy that powers the sun and stars. Researchers at the Lawrence Livermore National Laboratory in California for the first time produced more energy in a fusion reaction than was used to ignite it, something called net energy gain, the Energy Department said. The achievement will pave the way for advancements in national defense and the future of clean power, Granholm and other officials said. This is a landmark achievement for the researchers and staff at the National Ignition Facility who have dedicated their careers to seeing fusion ignition become a reality, and this milestone will undoubtedly spark even more discovery, Granholm said at a news conference in Washington. "The fusion breakthrough "will go down in the history books,'' she said. White House science adviser Arati Prabhakar, appearing with Granholm, called the fusion ignition a tremen

Gravitation of sun, moon influences behaviour of animals, plants: Study

NASA-launched spacecraft enters Sun's corona for first time in history

A spacecraft launched by NASA has done what was once thought impossible. On April 28, the Parker Solar Probe successfully entered the corona of the Sun -- an extreme environment that's roughly 2 million degrees Fahrenheit.A scientific paper describing the milestone was published in the Physical Review Letters.The historic moment was achieved thanks to a large collaboration of scientists and engineers, including members of the Center for Astrophysics | Harvard & Smithsonian (CfA) who built and monitor a key instrument on board the probe: the Solar Probe Cup. The cup collects particles from the Sun's atmosphere that helped scientists verify that the spacecraft had indeed crossed into the corona."The goal of this entire mission is to learn how the Sun works. We can accomplish this by flying into the solar atmosphere," said Michael Stevens, an astrophysicist at the CfA who helps monitor the cup. "The only way to do that is for the spacecraft to cross the outer boundary, which ...

Mars to be opposite, closest to Sun on October 13

Planet Mars will be opposite and closest to the Sun in the sky on October 13.On that date, Mars will be at opposition -- opposite the Sun in the sky. Earth will be situated directly between Mars and the Sun. As a result, Mars will rise as the Sun sets and sets as the Sun rises, according to Sky & Telescope.Opposition -- the most significant Martian date on stargazers' calendars -- is also when the planet is at its brightest and near its maximum apparent size in telescopes. Because of the shapes and orientations of the planets' orbits, however, Mars and Earth were actually closest on Tuesday, October 6, separated by just 62 million kilometres, said Sky & Telescope.For Mars, it is more than 160 times farther than the Moon. The planet would not be this near us again until 2035.Mars oppositions occur at roughly 26-month intervals when Earth catches up to Mars as the planets circle the Sun.This year's opposition is special because it occurs close to when Mars reaches the point .
