What if it’s cloudy or I’m not within the viewing area?
NASA will function a dwell stream of the eclipse from places throughout the globe! NASA may also host an episode of NASA Science Stay, from 11 p.m. – 12 a.m. ET. Watch right here:
What can I anticipate to watch?
UTC (Might 16) | EDT (Might 15-16) | PDT (Might 15) | Milestone | What’s Taking place? |
---|---|---|---|---|
1:32 | 9:32 p.m., Might 15 | — Moon not but seen | Penumbral eclipse begins | The Moon enters the Earth’s penumbra, the outer a part of the shadow. The Moon begins to dim, however the impact is kind of delicate. |
2:27 | 10:27 p.m. | — Moon not but seen | Partial eclipse begins | The Moon begins to enter Earth’s umbra and the partial eclipse begins. To the bare eye, because the Moon strikes into the umbra, it seems to be like a chew is being taken out of the lunar disk. The a part of the Moon contained in the umbra will seem very darkish. |
3:29 | 11:29 p.m. | 8:29 p.m. | Totality begins | Your complete Moon is now within the Earth’s umbra. The Moon will flip a coppery-red. Attempt binoculars or a telescope for a greater view. If you wish to take a photograph, use a digicam on a tripod with exposures of not less than a number of seconds. |
4:53 | 12:53 a.m., Might 16 | 9:53 p.m. | Totality ends | Because the Moon exits Earth’s umbra, the crimson shade fades. It should look as if a chew is being taken out of the other aspect of the lunar disk as earlier than. |
5:55 | 1:55 a.m. | 10:55 p.m. | Partial eclipse ends | The entire Moon is in Earth’s penumbra, however once more, the dimming is delicate. |

What else can I see tonight?
The Moon will probably be within the constellation Libra. Listed below are some extra skywatching suggestions for the month of Might.
Why does the Moon flip crimson throughout a lunar eclipse?
The identical phenomenon that makes our sky blue and our sunsets crimson causes the Moon to show crimson throughout a lunar eclipse. It’s referred to as Rayleigh scattering. Mild travels in waves, and totally different colours of sunshine have totally different bodily properties. Blue gentle has a shorter wavelength and is scattered extra simply by particles in Earth’s environment than crimson gentle, which has an extended wavelength.
Pink gentle, then again, travels extra instantly by means of the environment. When the Solar is overhead, we see blue gentle all through the sky. However when the Solar is setting, daylight should move by means of extra environment and journey farther earlier than reaching our eyes. The blue gentle from the Solar scatters away, and longer-wavelength crimson, orange, and yellow gentle move by means of.
Throughout a lunar eclipse, the Moon turns crimson as a result of the one daylight reaching the Moon passes by means of Earth’s environment. The extra mud or clouds in Earth’s environment through the eclipse, the redder the Moon will seem. It’s as if all of the world’s sunrises and sunsets are projected onto the Moon.
Artist’s depiction of the Earth throughout a lunar eclipse from the floor of the Moon. When considered from the Moon, as on this animation, the Earth hides the Solar. A crimson ring, the sum of all Earth’s sunrises and sunsets, strains the Earth’s limb and casts a ruddy gentle on the lunar panorama. With the darkness of the eclipse, the celebrities come out. The town lights of North and South America are seen on the night time aspect of the Earth. The a part of the Earth seen on this animation is the half the place the lunar eclipse might be seen.

Will any NASA spacecraft observe the eclipse?
NASA’s mission crew for the Lunar Reconnaissance Orbiter (LRO), NASA’s spacecraft in orbit across the Moon, will flip the devices off through the eclipse. The spacecraft is solar-powered, so LRO will energy right down to protect its battery whereas the Moon is in shadow.
The Lucy spacecraft, at the moment on its journey to review Jupiter’s Trojan asteroids, will flip its gaze towards its residence planet to watch a portion of the five-hour lengthy eclipse – from simply earlier than the penumbral eclipse to only earlier than the tip of totality. The mission crew plans to seize a view of each the Earth and the Moon with the high-resolution imager, L’LORRI. Because the spacecraft will probably be 64 million miles away and makes use of the Deep House Community, it's going to probably take a couple of weeks to obtain and course of the photographs.
