What if Mycroft is really two people, twins, and different scenes we’ve seen him in so far have actually featured two separate “Mycrofts” and one is him and one is his twin and there’s a mean ruthless “Caring is not an advantage” one and a kind caring “Your loss would break my heart” and one’s a “he’s secretly pleased to see you under all that” and one’s a “get out of my house, you reptile”.
Are stars better appreciated for their art after they die? Actually, stars usually create their most artistic displays as they die. In the case of low-mass stars like our Sun and M2-9 pictured above, the stars transform themselves from normal stars to white dwarfs by casting off their outer gaseous envelopes. The expended gas frequently forms an impressive display called a planetary nebula that fades gradually over thousands of years.
M2-9, a butterfly planetary nebula 2100 light-years away shown in representative colors, has wings that tell a strange but incomplete tale. In the center, two stars orbit inside a gaseous disk 10 times the orbit of Pluto. The expelled envelope of the dying star breaks out from the disk creating the bipolar appearance. Much remains unknown about the physical processes that cause planetary nebulae.
