This would be around 4:03 AM ET, which is the best time to see the red colour. Since the moon is in its apogee, it would appear small, but during the peak of the eclipse it would turn red. Since the drop in temperature is dependent on several factors such as how rocky the lunar surface is, how densely packed the soil is and its mineral composition, this kind of analysis during a lunar eclipse sheds more light on the moon’s regolith. Instruments aboard Nasa’s Lunar Reconnaissance Orbiter (LRO) can record how quickly specific areas on the moon cool off during an eclipse. Lunar eclipses also offer scientists the opportunity to study what happens when the surface of the moon is devoid of sunlight and cools quickly. ![]() Records kept of ancient solar and lunar eclipses – from the time when such notes were made in clay tablets – have more recently enabled modern astronomers to discover that the speed at which Earth spins on its axis has slowed by 1.8 milliseconds per day over the course of a century. Greek astronomer and mathematician Hipparchus of Nicaea discovered that the positions of constellations in the night sky changed in a 26,000-year cycle, by studying eclipses. The lunar eclipse is one of the many light-and-shadow tricks in the solar system that has helped guide humanity’s understanding of the cosmos for several millennia.Īristotle was one of the first to argue that the Earth was spherical based on the observation that the shadow of the Earth falling on the moon is always circular in shape. What scientists have learned from lunar eclipses Nasa is planning to send astronauts to the Moon in 2025 at the earliest as part of the Artemis mission, and there are two lunar eclipses predicted for the year. Since lunar eclipses substantially cool down the Moon, studying these changes can help scientists develop better equipment for future missions and experiments that can better survive extreme changes in temperatures. Since during a lunar eclipse the Earth filters the Sun’s light onto the Moon, our planet is essentially projecting thousands of sunrises and sunsets onto the lunar surface. Previous simulations by Nasa have revealed how astronomers on the moon would hypothetically view the occurrence of a total lunar eclipse. This would be the longest partial lunar eclipse in 580 years. About 99.1% of the moon will pass into the inner part of the Earth’s shadow – the umbra. On 19 November, Earth would pass between the Sun and the Moon and cause a near-total lunar eclipse. What astronomers on the moon would hypothetically see during a lunar eclipse The peak of the eclipse would begin around 3:45 AM ET till about 4:20 AM ET, according to Nasa. You can watch the eclipse live on Griffith Observatory’s channel This would begin to look like a bite is being taken out of the lunar disk, and a portion of the Moon inside the umbra has started appearing very dark. The Moon has begun to enter the Earth’s umbra – the inner part of the Earth’s shadow – and the partial eclipse has begun. How to see the lunar eclipse across the world What time will the lunar eclipse take place? What makes a ‘blood moon’ red and is it dangerous to look at it? Key points Lunar eclipse of Beaver ‘blood’ Moon will be longest in 580 years You can follow all the latest Moon action right here. and the end at 1:29 p.m., lasting for a total of three hours and six minutes.The whole event will be visible across the US but the arrival of the Sun on Friday morning will prevent people in the UK from seeing the latter half of it. The maximum view in North Texas will be at 11:52 a.m. pacific time and ends in Texas at 12:03 p.m. The annular solar eclipse begins in Oregon at 9:13 a.m. until June 21, 2039, though Alaska will be the only state in that eclipse’s path. This is the last annular solar eclipse that will be visible from the U.S. When the Sun forms a “ring of fire” around the Moon, it will be visible along a narrow path that crosses the U.S. It happens when the Moon moves between the Sun and Earth while it is at its furthermost point from Earth. The annular solar eclipse follows the total eclipse in August 2017 and precedes the total eclipse coming in April 2024. A total lunar eclipse occurs when the Earth’s shadow envelops the Moon, making it a coppery red, which is why it is known as a blood moon. We can then see Earth’s shadow on the Moon. It can only happen when the Moon is in the full phase. An eclipse of the Moon takes place when Earth lines up directly between the Sun and Moon, preventing the Sun’s light from getting to the Moon. ![]()
