On Wednesday, April 24th, Bengaluru residents will experience a rare celestial phenomenon known as Zero Shadow Day. The unique astronomical event, occurring between 12:17 pm and 12:23 pm, causes vertical objects to cast no shadows as the sun aligns perfectly overhead. This phenomenon occurs twice a year in regions between the Tropic of Cancer and the Tropic of Capricorn, with Bengaluru experiencing it around April 24/25 and August 18 annually.
The Lyrid meteor shower, one of the oldest and most reliable, is still visible in the Northern Hemisphere through April 29. Additionally, the full ‘pink moon’ will reach its peak on Tuesday, April 26, although it won’t actually appear pink.
A team of astronomers has discovered an Earth-sized planet orbiting a nearby star, GJ 887. The planet, designated GJ 887 b, is located in the habitable zone of its star, meaning that it could potentially support liquid water on its surface. This discovery is significant because it is the first time an Earth-sized planet has been found in the habitable zone of a star other than our own.
The current understanding of our solar system having eight planets may be challenged in the future. Astronomers are studying a celestial body that could potentially qualify as a ninth planet.
In addition to a total solar eclipse, the return of the ‘devil comet,’ and potential northern lights displays, astronomers predict an extraordinary celestial event in 2024: the eruption of a star system 3,000 light-years away, creating the illusion of a ‘new star’ near the constellation Hercules. T Coronae Borealis (T CrB), also known as the ‘Blaze Star,’ undergoes explosive events every 79 years, and astronomers believe its next eruption is imminent.
The MeerKAT radio telescope, located in the heart of South Africa’s Karoo region, is a testament to innovation and scientific excellence. With 64 dishes and exceptional sensitivity, MeerKAT has made remarkable contributions to both South African and international science. Its discoveries include the detection of magnetic filaments surrounding the supermassive black hole in the Milky Way, the identification of giant radio galaxies, and the discovery of an OH megamaser in a distant galaxy. Beyond its scientific impact, MeerKAT is also a driving force for human capital development, fostering collaboration and nurturing a new generation of African scientists and engineers.
