Most of the time, the stars look the same from night to night. Sometime over the next six months, though, there's a good chance you'll see a new bright star in the constellation Corona Borealis! (I've simulated the before & after view here.) blogs.nasa.gov/Watch_the_Sk... 🔭🧪

The constellation Corona Borealis.
The constellation Corona Borealis will get a bright new temporary star when nova T Coronae Borealis lights up.

T Coronae Borealis is a recurring nova -- a thermonuclear bomb that goes off every 80 years. Based its behavior last time, astronomers project that it's likely to explode in April-May. But these things are not completely predictable! www.aavso.org/news/t-crb-p... 🔭🧪

Light curve for the nova T Coronae Borealis. This plot has 4330 Johnson B-band magnitudes (blue diamonds) and 12,734 Johnson V-band magnitudes (green diamonds) all with CCD cameras from 2021.0--2023.5, all binned into 2 day time bins.  The usual ellipsoidal modulations (~0.4 mag full-amplitude as a sinewave at half the orbital period) are shown as the thick black curves, one for each of the bands.  The variations on all time-scales around the ellipsoidal light curves are normal for T CrB (even back to 1867), with these flickering being larger in the B-band.

Are you sure you're not just watching an 80s movie from Orion Pictures?

Wow! This was not on my bucket list.

Living in the τ Coronae Borealis must be interesting 😂 (yes, I know that life is highly improbable there, but nevertheless…)

Yeah, but check out MY simulated AFTER view, Science Boy!

The constellation Corona Borealis will get a bright new TOTALLY FAKE star when nova Andrew opens Photoshop.
