How far away is Deneb from Altair?
The three stars have been recognized for some time as having similar brightness (although it should be noted that Deneb is about 1,400 light-years away while Vega and Altair are roughly 20 light-years away each, showing how much more luminous Deneb is.)

What is the brightest star in the sky?
Vega is the brightest star of an otherwise dim and small constellation, Lyra (the Harp). Vega is one of the brightest stars in the night sky. (Sirius is the brightest in the night sky, but appears in the winter of the Northern Hemisphere.)

Does Altair rotate?
Altair also rotates fairly quickly and has flattening at its poles, which astronomers spotted in 2006 using long-baseline interferometery (which links together numerous telescopes to together look at a region of the sky.) In 2014, the XMM-Newton mission observed Altair, showing that the star has a corona (outer atmosphere) that changes depending on magnetic and rotational activity.
Is Vega a fast rotating star?
Vega is also a fast rotater. In 2006, astronomers discovered it is whirling around so quickly — every 12.5 hours — that its equator is many thousand degrees cooler than its poles. If the star rotated just 10 percentage points faster, it would be at its critical rotation speed — the point at which the star would self-destruct due to its fast rotation. The star is sometimes cited in the literature as a comparison to the rotation of other stars, such as the slowly rotating KIC 11145123.

Meteors from the Northern Taurids shower, which appear worldwide from October 13 to December 2 annually, will reach a maximum rate of about 5 per hour on Friday, November 12. The long-lasting, weak shower is the second of two consecutive showers derived from debris dropped by the passage of periodic Comet 2P/Encke. The larger-than-average grain sizes of the comet’s debris often produce colorful fireballs. The best viewing time will occur at around 1 a.m. local time on Friday, when the shower’s radiant, located in northwestern Taurus, will be highest in the southern sky. At this year’s peak, a first quarter moon will set by midnight, favoring more meteors. Keep an eye out for Northern Taurids on Thursday evening, too.

What is the best time to see Mercury in 2021?
After sunset throughout the month of May, 2021 Mercury will be easily visible by Northern Hemisphere observers while it travels on the high side of a nearly vertical evening ecliptic plane. The speedy planet will climb away from the sun until mid-month, when it will be at peak visibility. In the second half of the month Mercury will descend sunward, passing much brighter and slower Venus near month-end. As the sky grows darker each night, look for Mercury low in the west-northwest as a white point of light shining some distance above Venus. Since the planet will be traversing the space between us and the sun, telescope views of Mercury in May will show that its disk is growing larger while waning in illuminated phase (inset).
