A place in the sun
The Supreme Court of India has been at the centre of national debate for many unprecedented reasons in the last one year. Among them, the Apex Court’s approach towards ensuring gender justice has been a major one and widely appreciated. For instance, in less than a year we have seen the Supreme Court’s decision empowering...

Slowing down
The smallest celestial objects sometimes change their state of orbit or spin. The night sky has been long regarded as unchanging and even planets, the objects that move, are remarkably regular in their motion. We do know that the Earth has been gradually slowing in its rate of spin and gently closing in towards the...

New star may help decode Sun’s effect on Earth’s climate
Scientists have found a star that is almost identical to the Sun, except for the chemical composition, making it a ‘Rosetta Stone’ for the study of the solar body’s variability and effect on the Earth’s climate. The spots on the surface of the Sun come and go with an 11-year periodicity known as the solar...

Sun-like stars calm down after turbulent youth
Sun-like stars and their less massive cousins calm down surprisingly quickly after a turbulent youth, making the atmosphere more suitable for evolution of life, says a new study. The researchers used data from NASA’s Chandra X-ray Observatory and European Space Agency’s XMM-Newton to see how the X-ray brightness of stars similar to the Sun behaves...

Scientists to capture sunspot images during solar eclipse
During the upcoming total solar eclipse on August 21, a team of solar physicists are planning to capture high-resolution sunspots — the visible concentrations of magnetic fields on the Sun’s surface — at microwave radio wavelengths. Sunspots are the primary generator of solar flares, the sudden, powerful blasts of electromagnetic radiation and charged particles that...

Sun’s core rotates four times faster than its surface
An international team of astronomers has found that the Sun's core rotates nearly four times faster than the solar surface. The discovery was possible with European Space Agency (ESA) and NASA's Solar and Heliospheric Observatory, or SOHO, which helped the solar scientists find evidence of a type of seismic wave in our Sun. These low-frequency...

Distant comets more common than previously thought
Large comets that take more than 200 years to make one revolution around the Sun are more common in the universe than previously thought, a new study conducted by the US space agency NASA has said. Based on observations by the agency's WISE spacecraft, the study found that the number of long-period comets measuring at...

Scientists to chase solar eclipse using NASA’s research jets
For the upcoming total solar eclipse, a team of NASA-funded scientists are planning to observe the solar corona using stabilised telescopes aboard two of the space agencys research aircraft. Scientists, led by Amir Caspi from the Southwest Research Institute in Colorado, will use two of NASA's retrofitted WB-57F research jets to follow the shadow of...

NASA issues safety tips to view solar eclipse
People who plan to view the solar eclipse should check the safety authenticity of viewing glasses to ensure they meet basic safety standards, NASA has recommended. A total solar eclipse, which is when the Moon completely covers the Sun, will occur across 14 states in the continental US on August 21, along a 112 km-wide...

Higher sun exposure may increase risk of eye freckles
A higher lifetime exposure to sunlight may increase the risk of developing eye freckles or dark spots on the coloured part of the eye called iris, a study has warned. While not malignant, eye freckles could indicate the presence or risk of sunlight-triggered eye diseases like cataract or macular degeneration, researchers said. Over 600 swimmers...

This micro animal can outlive the Sun
Scientists have identified an eight-legged micro-animal — Tardigrade — touted as the world's most indestructible species, one that can survive until the Sun dies. The study showed that Tardigrades — also known as the water bear — are tiny creatures that can grow to a maximum size of 0.5mm, best seen under a microscope, and...

Here comes the sun
From prayer and sacrifice to sunbathing, humans have worshipped the sun since time immemorial. And it’s no wonder. At around 150m km away, it is close enough to provide the light, heat and energy to sustain the entire human race. But despite the fact that our parent star has been studied extensively with modern telescopes...

Citizen scientists uncover cold new world near Sun
A brown dwarf over 100 light years away from the Sun has been discovered using a new citizen-science tool that helps astronomers pinpoint new worlds lurking in the outer reaches of our solar system. Just six days after the launch of the Backyard Worlds: Planet 9 website in February, four different users alerted the science...

NASA to launch world’s first mission to Sun in 2018
NASA is set to launch the world's first mission to the Sun next year, that will explore our star's atmosphere and answer questions about solar physics that have puzzled scientists for over six decades. The Parker Solar Probe has been named in honour of pioneering astrophysicist Eugene Parker, who predicted the existence of the solar...
