A New Telescope Can Observe Even in Broad Daylight

Astronomy is a profession that, so far, has only been done at night, at least on Earth. Light from the Sun overwhelms any light from other stars, making it impractical for both professional and amateur astronomers to look at the stars during daytime. There are several disadvantages to this, not the least of which is that many potentially exciting parts of the sky aren’t visible at all for large chunks of the year as they pass too close to the Sun. To solve this, a team from Macquarie University, led by graduate student Sarah Caddy, developed a multi-camera system for a local telescope that allows them to observe during daytime.

A Nova in the Making: Will T Coronae Borealis Pop in 2024?

If predictions are correct, a key outburst star could put on a show in early 2024.

If astronomers are correct, a familiar northern constellation could briefly take on a different appearance in 2024, as a nova once again blazes into prominence. The star in question is T Coronae Borealis, also referred to as the ‘Blaze Star’ or T CrB. Located in the corner of the constellation Corona Borealis or the Northern Crown, T CrB is generally at a quiescent +10th magnitude, barely discernible with binoculars… but once every 80 years, the star has flared briefly into naked eye visibility at around +2nd magnitude.
