The annual Lyrid meteor bathe peaks tonight. Its radiant, positioned close to brilliant Vega in Lyra the Lyre, rises round 8 P.M. native time. For the most effective nighttime viewing of the bathe, you’ll wish to let that radiant get as excessive as attainable, so wait till late this night earlier than stepping exterior to observe for capturing stars.
Sadly, the radiant received’t get very excessive earlier than midnight; when you’re prepared to remain out into the early hours of tomorrow morning or alternatively stand up a number of hours earlier than the Solar on the twenty third, your prospects can be a bit higher. Early morning is all the time greatest to view meteor showers, as that’s when Earth’s rotation leads to faster-moving bathe meteors with longer trails. Lyrid meteors sometimes transfer by way of our ambiance at speeds of about 30 miles (50 kilometers) per second — not significantly quick, so far as meteors go.
The Moon received’t intrude together with your viewing late this night, bumping up your probabilities of recognizing extra meteors. Nonetheless, the Lyrids’ most fee at peak is simply about 18 meteors per hour — and that quantity can be decrease in actuality, because the radiant is not going to sit immediately overhead.

Final Quarter Moon happens at 7:56 A.M. EDT. This lunar part is characterised by early-morning rise instances, which means nighttime is now the proper setting to view fainter, deep-sky objects.
In the present day, although, your night goal is a brilliant magnitude –0.4: the planet Mercury. This month brings us the tiny planet’s greatest night apparition of 2022, and it’ll attain biggest elongation from the Solar in only a few days. However first, tonight presents a novel likelihood to step again by way of time and think about mercury as Giovanni Schiaparelli noticed it 140 years in the past.
Schiaparelli started learning Mercury in 1882 and instantly noticed what he believed was an enormous determine 5 function on the planet’s darkish floor. In the present day, Mercury presents to us an almost equivalent view to what Schiaparelli noticed in early 1882.
Begin by finding Mercury, which stands almost 20° above the western horizon at sundown. It’s the primary brilliant spot that may seem after sundown, making it straightforward to search out. The planet units round 9:30 P.M. native time and the most effective views will come earlier fairly than later, as twilight is fading and Mercury is larger above the turbulent air on the horizon.
Zoom in on Mercury with any telescope and also you’ll see the planet’s 6.8″-wide disk is 56 p.c lit, as in comparison with the 7.0″-wide, 53-percent-lit planet Schiaparelli noticed on Feb. 6, 1882. The longitude of Mercury’s central meridian tonight is 85°, in contrast with 86° in 1882. And when you have a bigger telescope (6 to 10 inches), a glance by way of the eyepiece will transport you squarely into Schiaparelli’s footwear, providing the identical stage of element. Do you see the darkish determine 5, or the intense spot of the crater Kuiper, which sits close to the limb, simply left of the 5?
