India's monsoon rainfall forecast to be above average in September

Image
  India is likely to receive above average rainfall in September, the state-run weather office said on Wednesday, helping millions of farmers who had to endure patchy rains in July and August. Monsoon rains were 10% above average in June. "According to critical weather parameters, rains are most likely to be above normal in September this year," Mrutyunjay Mohapatra, Director General of the India Meteorological Department (IMD), told a news conference. The IMD defines average, or normal, rainfall as between 96% and 104% of a 50-year average of 88 cms (34 inches) for the four-month season beginning in June. After lashing the southernmost Kerala coast on June 3, the monsoon spread to two-thirds of India by the end of the first half of the month, nearly 15 days earlier than expected. And then it tapered off in the third week of June. Read More  

ISRO demonstrates free space quantum communication for the first time

Image
  The Indian Space Research Organisation (ISRO) recently demonstrated free-space quantum communication over a distance of 300 m for the first time. The demonstration included live videoconferencing using quantum-key-encrypted signals. This is a major achievement for unconditionally secured satellite data communication using quantum technologies. Isro said that a number of key technologies were developed indigenously to accomplish this major feat, which included the use of an indigenously developed navigation satellite system, with an operational name of NavIC, a receiver for time synchronisation between the transmitter and receiver modules, and gimbal mechanism systems instead of bulky large-aperture telescopes for optical alignment.

Isro working on green fuels like hydrogen peroxide for rockets

Image
  The Indian space rockets are set to go green as ISRO is working to replace its existing hazardous fuel with non-hazardous and environment- friendly fuels for its rockets and satellites, the ISRO Chairman said. He also said that the Indian Space Research Organisation (ISRO) is looking at green propulsion through hydrogen peroxide in its rocket that would take Indians into the space under its 'Gaganyaan' mission. "Since humans will be inside the rocket, we want only non-hazardous fuel and not the hazardous one to power the human space mission's Gaganyaan rocket ," ISRO chief K Sivan, who is also Secretary in Department of Space, told IANS. According to him, ISRO is also looking at rocket engines powered by hydrogen peroxide as a mono-propellant or as a bi-propellant along with ethanol. ISRO is also developing another green fuel - LOX/Methane- liquid oxygen as oxidiser and methane as fuel. Read More

Great Conjunction: How you can watch as Jupiter, Saturn align tonight

Image
  After a fast paced race to Mars and plans to return to the moon, there is still something left for science and astronomy enthusiasts in 2020, a rare celestial phenomenon —the Great Conjunction— when Jupiter and Saturn will align to form one of the brightest stars in the night sky on Monday being seperated by just one-tenth of a degree. The planets regularly appear to pass each other in the solar system, with the positions of Jupiter and Saturn being aligned in the sky about once every 20 years. However, this year the conjunction is special as it’s been nearly 400 years since the planets passed this close to each other in the sky, and nearly 800 years since the alignment of Saturn and Jupiter occurred at night. The rare phenomenon can be visible globally including in India between 6:30-7:30 pm. The planets will be easy to see with naked eye by looking toward the southwest just after sunset. Jupiter bigger and closer to Earth will be vastly brighter. Read More

Lunar Eclipse 2020: Interesting facts about today's penumbral lunar eclipse

Image
  Lunar Eclipse 2020 : A lunar eclipse will take place today. This year, a total of four penumbral lunar eclipses were expected to take place, out of which the first lunar eclipse took place on January 10, the second on June 5 and the third on July 5. The fourth one will occur today. "A penumbral lunar eclipse takes place when the sun, earth, and moon align in almost a straight line. The earth blocks some of the sun's light from directly reaching the moon's surface, and partially covers the moon with the outer part of its shadow, also known as the penumbra," Rajendraprakash Gupt, superintendent of Jiwaji Observatory in Ujjain in Madhya Pradesh said. At what time will the lunar eclipse take place The 'penumbral lunar eclipse' will begin at 12:59:09 pm and continue till 05:25:09 pm today. Lunar Eclipse 2020: Which countries will witness it? The lunar eclipse will be seen in most of Europe, most of Asia, Australia, North America, South America, Pacific, ...

Nokia to provide 4G network on Moon: Why it is bad news for radio astronomy

Image
  As you drive down the road leading to Jodrell Bank Observatory , a sign asks visitors to turn off their mobile phones, stating that the Lovell telescope is so powerful it could detect a phone signal on Mars. Radio telescopes are designed to be incredibly sensitive. To quote the legendary astronomer Carl Sagan, “The total amount of energy from outside the solar system ever received by all the radio telescopes on the planet Earth is less than the energy of a single snowflake striking the ground.” The total energy now is probably a few snowflakes’ worth, but nevertheless it is still true that astronomical radio signals are typically magnitudes smaller than artificial ones. If Jodrell Bank could pick up interference from a phone signal on Mars, how would it fare with an entire 4G network on the Moon? That is the issue that is worrying astronomers like me, now that Nokia of America has been awarded US$14.1m (£10.8m) for the development of the first ever cellular network on the M...
