Star HD 142527 probably struggles to find maternity clothes in its size.
A team of scientists from Japan’s Osaka University has been observing the star from Chile’s ALMA observatory, where they’ve noticed some pretty unusual cosmic behavior. Star HD 142527 is over 450 light years away and is surrounded by a ring of dust and gas. That ring isn’t uniform — in fact, the northern part of it is brighter and denser than the rest. That portion of the ring is over 20 billion kilometers away from the star itself, which surprised the team. The astronomers have never before observed such a dense collection of material in a ring so far away from the central star. In this case, that dense knot is about five times as far from the star as Neptune is from the sun.
