About this listen

Episode 2 (2026-02-17) What we cover 1) Space mystery: shock waves around a white dwarf • A white dwarf is the super-dense leftover core of a Sun-like star. • Astronomers found bow-shaped patterns (“shock waves”) in glowing gas. • Scientists are investigating what could be powering the ripples (movement through gas, a companion star, or another source). 2) Annular solar eclipse: the Sun as a bright ring • In an annular eclipse, the Moon looks slightly smaller (it’s farther away in its orbit), leaving a bright ring of Sun. • Best viewing mentioned: Antarctica, with partial views in parts of southern South America and southern Africa. • Safety for families/classrooms: Never look at the Sun directly. Use ISO-certified eclipse viewers/solar filters; regular sunglasses are not safe. A pinhole projector is a safe alternative. 3) Mahashivratri in Mandi, India • A week-long cultural festival that begins with a procession and ceremonies. • Many communities participate by bringing symbols or statues as part of tradition. • Helpful vocabulary: “procession” = a planned, organized walk/celebration. Talk-about-it questions • If you could ask a scientist one question about space, what would it be? • What’s one tradition your family enjoys, and why does it feel special?
