In the Never underestimate an old woman who loves drag racing and was born in september moon blood quote shirt process of searching for life in distant worlds, astronomers are exploiting a huge and nearby tool – our own moon.
During last year’s total eclipse, astronomers trained the Hubble Space Telescope on our moon, which serves as a giant moon mirror. This marks the first time that a space telescope has captured a total lunar eclipse, and the exercise could even help us track life elsewhere in the universe.

Unlike a total eclipse, when the moon slips between the sun and the Earth, our planet will lie between the sun and the moon during a total lunar eclipse. When the Never underestimate an old woman who loves drag racing and was born in september moon blood quote shirt Earth blocks the moon’s view of the sun, only rays of light can pass through the planet’s atmosphere and cast shadows on the Moon’s surface.
Hubble’s observations of a cosmic clock display, the Never underestimate an old woman who loves drag racing and was born in september moon blood quote shirt first of its kind, were detailed in a study published last week in the Journal of Astronomy.
“We want to see Earth as an alien and observe a portion of the Earth’s spectrum that has never been observed this way before,” said Giada Arney of NASA’s Goddard Space Flight Center, said co-author of the scientific paper. That way, this technique can be applied to actual exoplanets.
Earth serves as the perfect – and only – analogue to finding life on other planets. The researchers realized that the light reflected from the Moon would be similar to what they are currently looking for: light passing through the atmosphere of a distant world as it passed in front of its host star. . Arney says it’s a similar geometry of what happens during a local eclipse. In other words, researchers are looking to find out what our planet might look like if an alien observer looked at Earth from light years away.
Thanks to Hubble’s gaze, the scientists were able to analyze an important chemical during the eclipse: ozone. Previous discoveries of Earth’s ozone layer have always come from our side here on the ground, accompanied by distortion from other parts of the atmosphere. From its unique vantage point in space, Hubble was able to eliminate that distortion by scanning the ultraviolet rays reflected from the moon during a lunar eclipse. Ozone is three oxygen atoms linked together; it is created when the sun shatters molecular oxygen, O2, with ultraviolet rays, rearranging that atomic pair into a trio – creating ozone. A large network of ozone molecules called the ozone layer acts as a protective shield from the Sun’s ultraviolet radiation.
The presence of ozone is often direct evidence of life – for example, plants emit molecular oxygen on Earth through photosynthesis, which transforms into ozone in the Never underestimate an old woman who loves drag racing and was born in september moon blood quote shirt atmosphere. So if we see ozone in the atmosphere of an alien planet, Arney adds, that might suggest photosynthesis is going on there as well.
“These new Hubble observations demonstrate that a strong enough observatory will be able to identify ozone fingerprints in the spectrum of the,” said Edward Schwieterman, assistant professor of astrophysics at the University of California. a distant planet like Earth transitions its host star ”. at Riverside, who were not involved in the Never underestimate an old woman who loves drag racing and was born in september moon blood quote shirt study. “This research is an important contributor to this field because previous observations of the Earth’s transmittance spectrum were mainly in the near infrared, where ozone absorption was less noticeable.”
Of course, we already know that ozone surrounds the Earth. But the Never underestimate an old woman who loves drag racing and was born in september moon blood quote shirt new study suggests the most powerful molecule detection so far. Hubble can look at the ultraviolet light of the spectrum, which is absorbed by our atmosphere and cannot be seen with telescopes on the ground.
