HTTP:: Spitzer Watches Forming Exoplanet in Real Time
--------
When new stars are born, not all material in their precursors gets ignited and consumed. The remains usually start spinning around it, and, over millions of years, new planets are formed. The debris-filled areas around the stars are known as a protoplanetary disk. Astronomers know how long it takes for planets to form from these structures, and therefore were amazed to see that a cloud of dust and gas around the young, new star LRLL 31 was being pushed around, Space reports. There are, in fact, two things that make the find amazing. For starters, discovering significant motions in a space structure via telescope measurements taken only five months apart is extremely rare. This usually means that the observed target is moving or otherwise evolving very fast. Secondly, a moving clump of material could only be generated by two things, experts say, either a new star forming near the first one, or a new exoplanet forming from that clump. If the latter turns out to be true, then!
these are the first, real-time measurements of how planets form from protoplanetary disks. “We don't know if planets have formed, or will form, but we are gaining a better understanding of the properties and dynamics of the fine dust that could either become, or indirectly shape, a planet. This is a unique, real-time glimpse int...
