Hidden cozied up to #Betelgeuse, a bright red #star in the constellation Orion, astronomers may have finally found the giant star’s long-sought companion.

This close-orbiting partner, first postulated over a century ago, matches some predictions and adds another piece to the puzzle of the mysterious supergiant star.

The companion appears to orbit the supergiant at a distance just four times that between Earth and the sun, putting the companion within Betelgeuse’s expansive outer #atmosphere.

Science News · Betelgeuse’s companion star revealed in new imagesRevealed by advanced imaging, the long-sought "Betelbuddy" is much smaller and fainter than Betelgeuse and orbits within the supergiant’s atmosphere.

Astronomers may have caught a still-forming #planet in action, carving out an intricate pattern in the gas and dust that surrounds its young host #star.

They observed a planetary disc with prominent spiral arms, finding clear signs of a planet nestled in its inner regions.

This is the first time astronomers have detected a planet candidate embedded inside a disc spiral.

Observations of #HOPS315 align with theories of how our own #solarsystem began to take shape
"This is the first time that #astronomers have been able to see details of the inner structure of such a system. This provides an opportunity to study how planetary systems such as ours were shaped in the first stages of their existence."

#CitizenScientists pinpoint 10,000 eclipsing #star pairs
#NASA is still looking for #volunteer stargazers to help with the #astronomy effort
#Ctizenscience project in question, the #EclipsingBinaryPatrol, validates images from NASA's Transiting Exoplanet Survey Satellite (TESS) mission. Researchers identified 1.2 million potential eclipsing star pairs. Citizen scientists validated a subset of about 60,000... manually inspecting 100,000s of images.

The Washington Post · Citizen scientists pinpoint 10,000 eclipsing star pairsOverall, the citizen scientists identified 10,001 eclipsing binary pairs. Of those, 7,936 were previously unknown.

Will I find weird star colors in non-typical stars?

1st photo - Zeta Herculis and Beta Draconis - high metallicity stars. North is to the left and captures the keystone asterism in Hercules in the upper right of the frame and the head of Draco in the lower left. High metallicity stars have more absorption features in their spectra compared to low metallicity stars.

To my eye, they don't exhibit weird color that is different than all the other stars in the frame.

2nd photo - finder chart with these two stars circled in red.

3rd photo - Omicron Draconis is a star with emission lines in its spectrum. It's an RS Canum Venaticorum type of star and that is one of their defining characteristics. Again, it's color does not stand out as weird.

4th photo - finder chart.

I plan to image other emission line stars after monsoon ends.
