Hubble | 31 yrs in space

The Hubble Space Telescope was launched into space 24 April 1990. Astronomers recently aimed Hubble at one of the brightest known stars, AG Carinae, in the constellation Carina. This luminous blue variable lies about 20,000 lt-yr from Earth. It exploded about 10,000 yrs ago. The nebula surrounding the star contains the equivalent of about 15 times the mass of our Sun. The star has about 55 times the mass of our Sun. Scientists from NASA, ESA, and STScI made this color image by combining four color-filtered greyscale images listed at the left.


The following video was released by NASA Goddard to celebrate this occasion. It lasts about 5 minutes.

    • People wondered at first when they found the scope needed to be fitted with corrective lenses. Then, all was good. I am looking forward to the James Webb Space Telescope. It will see in infrared and allow farther look-back in time. The most distant Doppler Shifted galaxies are in the infrared.

  1. I hope they keep Hubble going as long as possible, even though JWT is due for launch later this year (I think). Something will malfunction eventually or its orbit will decay

    I’ve seen the reports on AG Carinae and its surrounding nebulosity. It looks like a planetary nebula but probably not caused by quite the same mechanism. As always, my first thoughts are: “can I capture it in my telescope”. Probably not but it may be worth a try.

I'd like to hear from you.
