How long is the solar system's longest day? Venus has the answer
The Hindu
The study found that a single Venusian rotation takes 243.0226 Earth days
Data obtained by bouncing radio waves off Venus — treating it, as one scientist said, like a giant disco ball — is providing new insight into Earth's closest planetary neighbour, including a precise calculation of the duration of a Venusian day. also measured the tilt of the Venusian axis and size of the planet's core, allowing for a deeper understanding of an enigmatic world sometimes called Earth's 'evil twin.'

How do you create a Christmas tree with crochet? Take notes from crochet artist Sheena Pereira, who co-founded Goa-based Crochet Collective with crocheter Sharmila Majumdar in 2025.

The collective’s multi-hued, 18-foot crochet Christmas tree has been put together by 25 women from across the State. “I’ve always thought of doing an installation with crochet. So, we thought of doing something throughout the year that would culminate at the year end; something that would resonate with Christmas message — peace, hope, joy, love,” explains Sheena.
