This image is of V1025 Tauri, a triple star system in the Taurus Molecular Cloud some 400-450 light years away; its Gaia EDR3 is 788 ly but that seems unlikely. The photographer noticed some faint nebulosity around the star, took a chance, and ended up with this picture--as an object it is virtually unstudied, with only one other widely available picture that I'm aware of.

Hubble Sees a Brand New Triple Star System

In a world that seems to be switching focus from the Hubble Space Telescope to the James Webb Space Telescope, Hubble still reminds us it’s there. Another amazing image has been released that shows the triple star system HP Tau, HP Tau G2, and HP Tau G3.  The stars in this wonderful system are young, … Continue reading "Hubble Sees a Brand New Triple Star System"

Universe Today
Now is time for the spectrum of a Wolf-Rayet type of star: WR-7 also catalogued as V1687 Cyg.
It is a WC, meaning that it is a star rich in carbon. We can actually "see" the carbon and helium inner layers, because the intense stellar winds and a pronounced unstable hydrostatic equilibrium have expelled its outer hydrogen layers to interstellar space. The broad emission lines are trademark of these types of stars.

Before the end 2022 (according to my time zone), allow me to share a final light curve for the rotational variable Star HD 251108.

These observations we're requested by the AAVSO in their Variable Alert #798.

May this domingo 2023 be full of amazing #astronomy discoveries, fun, and awe!

Testing my new #script for #variableStar #observation. Seems to pinpoint it. :-) #astronomy #astrophotography
Just did my first #photometric #variablestar #observation #report to #AAVSO. A new chapter in my #citizenScience endeavour.
