Astronomy Picture of the Day - The Outburst Clouds of Star AG Car

Explanation: What created these unusual clouds? At the center of this 2021 Hubble image, reprocessed by Judy Schmidt, sits AG Carinae, a supergiant star located about 20,000 light-years away in the southern constellation Carina. The star's emitted power is over a million times that of the Sun, making AG Carinae one of the most luminous stars in our Milky Way galaxy. AG Carinae and its neighbor Eta Carinae belong to the scarce Luminous Blue Variable (LBV) class of stars, known for their rare but violent eruptions. The nebula that surrounds AG Car is interpreted as a remnant of one or more such outbursts. This nebula measures 5 light-years across, is estimated to contain about 10 solar masses of gas, and to be at least 10,000 years old. This Hubble image, taken to commemorate Hubble's 31st launch anniversary, is the first to capture the whole nebula, offering a new perspective on its structure and dust content. The LBVs represent a late and short stage in the lives of some supergiant stars, but explaining their restlessness remains a challenge to humanity's understanding of how massive stars work.

That’s a lot of outbursts.

Anger management is recommended.

I have similar outbursts. Strange that they began on 11/04/20.

That is odd, me too.

The differences between different star types is pretty amazing.

If you'd read, the image was taken in visible and ultraviolet light. Ultraviolet light offers a slightly clearer view of the objects. Hubble uses ultraviolet-light observations because this wavelength range can only be viewed from space. Hubble’s directs light to its ultraviolet-visible light channel, which breaks down the light with filters into specific colors that are present. After the data is sent to Earth, those processing the data assign primary colors and reconstruct the data into a picture our eyes can clearly identify. It's all quite real, and they simply use these filters to bring out or enhance what our limited vision is not capable of seeing.
