Hubble Celebrates 29th Anniversary with a Colorful Look at the Southern Crab Nebula

In celebration of the 29th anniversary of the launch of NASA's Hubble Space Telescope, astronomers captured this festive, colorful look at the tentacled Southern Crab Nebula.

The nebula, officially known as Hen 2-104, is located several thousand light-years from Earth in the southern hemisphere constellation of Centaurus. It appears to have two nested hourglass-shaped structures that were sculpted by a whirling pair of stars in a binary system. The duo consists of an aging red giant star and a burned-out star, a white dwarf. The red giant is shedding its outer layers. Some of this ejected material is attracted by the gravity of the companion white dwarf.

The result is that both stars are embedded in a flat disk of gas stretching between them. This belt of material constricts the outflow of gas so that it only speeds away above and below the disk. The result is an hourglass-shaped nebula.

The bubbles of gas and dust appear brightest at the edges, giving the illusion of crab leg structures. These "legs" are likely to be the places where the outflow slams into surrounding interstellar gas and dust, or possibly material which was earlier lost by the red giant star.

Apart from Zeta Lyrae and Lyrae, which double star you observed last night is resolvable with my telescope?

Alpha Herculis: 3 mag + 5.4 mag star, distance 4.6 arcsec - I would say that this could not be problem for your telescope (however it will depends on seeing)
Gamma Virginis: two 3.5 mag stars, distance 2.8 arcsec - this could be resolvable for you too, 7 cm refractor is still enough for this distance
Izar: 2.5 mag + 4.9 mag star, distance 2.8 arcsec - depends on seeing, 2,8 arcsec is however there could be problem with different brightness of both stars (smaller star can be "flashed" by light of stronger star in case of such close doublestar)

all other are observable through 7 cm refractor without problem



Have you ever tried to observe A0620-00 in Monocerotis? :P It's a K5 V star and black hole system. Its apparent magnitude is 11.12.
Hmm, not tried.
Interesting, 11.2 mag would be no problem for my telescope.

Also, I see that sunspot 2738 is going to disappear from our view very soon.

I observed Jupiter again and tonoght it was gorgeous, many details of Jupiter's clouds system were visible. I also observed Saturn (at first time of this year), it's still very low above horizon, however thanks good sky conditions it was surprisingly good observable.
+ I observed few doublestars in spring and summer constellations (Mizar, Cor Caroli, Izar, Gamma Virginis, Alpha Herculis, Beta Lyrae, Zeta Lyrae and Albireo)

But look at the reaction of the audience. He enters the stage: everyone is screaming and then a complete silence, people are eager to hear what Ian is going to say. He tries to say something, takes a breath, opens his mouth and again incredible applause. Just amazing.

It was after Age of Extinction, the fifth one.
Yes...now i remembered!
Irayo nìtxan! ;)

No problem!! (can't find a translation for that in Na'vi, or, I would use that, LOL)

Yeah I really hope that they will go with the lore presented not only in the movies but also in comics and animated films.

And probably the best moment during the announcement  :)
