Using the MIDI instrument at the Very Large Telescope Interferometer of the European Southern Observatory (ESO) in the Atacama Desert of Chile, the research team obtained an unprecedented clear view of the warm dust in the nucleus of the Circinus

Niel Brandt, Distinguished Professor of Astronomy and Astrophysics, said that he was perplexed by the unusually strong evolution of the orbit of Circinus
X-1 since my graduate-school days, asserting that the discovery now of this system's youth provides a satisfying explanation for why its orbit evolves so strongly - as the system likely still is settling down after its violent birth.
Created by French astronomer Nicolas-Louis de Lacaille in 1752, Circinus
(the Drafting Compass) has a delicate shape formed by its three brightest stars: 3.
The remnant, called RCW 86, is located about 8200 light-years away towards the constellation of Circinus
(the Drawing Compass).
The shape of the Circinus
constellation resembles a long, acute-angled triangle with Alpha Circini pointing SW Beta and Gamma Circini completes the shape of the image, approximately 7 degrees NW.
It may be the fourth-smallest constellation, with an area of just 93 square degrees, but its proximity to Alpha Centauri and its distinctive shape make Circinus
a star figure that you can find with relative ease.
Also culminating at midnight around the middle of the month is the small southern constellation Circinus
the Compasses, located between the Pointers (alpha and beta Centauri) and the Southern Triangle (Triangulum Australe).
NGC 5822 lies about 2,400 light-years distant and is situated at the extreme southern end of Lupus, near the border with Circinus
