Encontrar ruinas y obtener fotografías junto a las estrellas es algo fantástico. Villacreces, Castilla y León, España. Villacreces fue el primer despoblado del siglo XX en Tierra de Campos.

La estructura que podemos ver en el centro es la Torre mudéjar.

Visto desde la luna de hielo Tetis , los anillos y las sombras mostrarían fantásticas vistas del sistema de Saturno. ¿No has visitado a Tethys últimamente? Entonces este hermoso paisaje en anillo de la nave espacial Cassini tendrá que funcionar por ahora. Atrapada por la luz del sol justo debajo y a la izquierda del centro de la imagen en 2005, la propia Tetis tiene unos 1.000 kilómetros de diámetro y orbita a menos de cinco radios de Saturno desde el centro del planeta gigante gaseoso.

This is Caldwell 109! 🎆🎆🎆

This “phantom snowball” planetary nebula shows ornate, beautiful shapes like spirals of gas that we’ll likely see when the Sun dies as well. It was also the last picture I needed to finish my Caldwell collection - such a great way to end a remarkable astrophotography experience! 🍭🍭🍭

NASA’s Search for Life: Astrobiology in the Solar System and Beyond

Are we alone in the universe? So far, the only life we know of is right here on Earth. But here at NASA, we’re looking.

We’re exploring the solar system and beyond to help us answer fundamental questions about life beyond our home planet. From studying the habitability of Mars, probing promising “oceans worlds,” such as Titan and Europa, to identifying Earth-size planets around distant stars, our science missions are working together with a goal to find unmistakable signs of life beyond Earth (a field of science called astrobiology).

Dive into the past, present, and future of our search for life in the universe.

Mission Name: The Viking Project

Launch: Viking 1 on August 20, 1975 & Viking 2 on September 9, 1975

Status: Past

Role in the search for life: The Viking Project was our first attempt to search for life on another planet. The mission’s biology experiments revealed unexpected chemical activity in the Martian soil, but provided no clear evidence for the presence of living microorganisms near the landing sites.

Mission Name: Galileo

Launch: October 18, 1989

Status: Past

Role in the search for life: Galileo orbited Jupiter for almost eight years, and made close passes by all its major moons. The spacecraft returned data that continues to shape astrobiology science –– particularly the discovery that Jupiter’s icy moon Europa has evidence of a subsurface ocean with more water than the total amount of liquid water found on Earth.

Mission Name: Kepler and K2

Launch: March 7, 2009

Status: Past

Role in the search for life: Our first planet-hunting mission, the Kepler Space Telescope, paved the way for our search for life in the solar system and beyond. Kepler left a legacy of more than 2,600 exoplanet discoveries, many of which could be promising places for life.

Mission Name: Perseverance Mars Rover

Launch: July 30, 2020

Status: Present

Role in the search for life: Our newest robot astrobiologist is kicking off a new era of exploration on the Red Planet. The rover will search for signs of ancient microbial life, advancing the agency’s quest to explore the past habitability of Mars.

Mission Name: James Webb Space Telescope

Launch: 2021

Status: Future

Role in the search for life: Webb will be the premier space-based observatory of the next decade. Webb observations will be used to study every phase in the history of the universe, including planets and moons in our solar system, and the formation of distant solar systems potentially capable of supporting life on Earth-like exoplanets.

Mission Name: Europa Clipper

Launch: Targeting 2024

Status: Future

Role in the search for life: Europa Clipper will investigate whether Jupiter’s icy moon Europa, with its subsurface ocean, has the capability to support life. Understanding Europa’s habitability will help scientists better understand how life developed on Earth and the potential for finding life beyond our planet.

Mission Name: Dragonfly

Launch: 2027

Status: Future

Role in the search for life: Dragonfly will deliver a rotorcraft to visit Saturn’s largest and richly organic moon, Titan. This revolutionary mission will explore diverse locations to look for prebiotic chemical processes common on both Titan and Earth.

A Total Solar Eclipse Over South America

On Dec. 14, 2020, a total solar eclipse will pass over Chile and Argentina.

Solar eclipses happen when the Moon lines up just right between the Sun and Earth, allowing it to cast its shadow on Earth’s surface. People within the outer part of the Moon’s shadow will see the Sun partially blocked by the Moon, and those in the inner part of the shadow will see a total solar eclipse.

The Moon’s orbit around Earth is slightly tilted, meaning this alignment doesn’t happen on every orbit. Total solar eclipses happen somewhere on Earth about once every 18 months.

During a total solar eclipse, the Moon blocks out the Sun’s bright face, revealing its comparatively faint outer atmosphere, the corona. This provides Sun-watchers and scientists alike with a rare chance to see the solar corona closer to the Sun’s surface than is usually possible.

Scientists can take advantage of this unparalleled view — and solar eclipses’ unique effects on Earth’s atmosphere — to perform unique scientific studies on the Sun and its effects on Earth. Several NASA-funded science teams performed such studies during the total solar eclipse in the United States on Aug. 21, 2017. Read about what they’ve learned so far.

Watching the eclipse

We’ll be carrying images of December’s eclipse — courtesy of Pontificia Universidad Católica de Chile — on NASA TV and on the agency’s website starting at 9:40 a.m. EST on Dec. 14.

We’ll also have a live show in Spanish from 10:30 – 11:30 a.m. EST featuring views of the eclipse and NASA scientists.

If you’re observing the eclipse in person, remember that it’s never safe to look directly at the uneclipsed or partially eclipsed Sun. You can use special solar viewing glasses (NOT sunglasses) or an indirect method like pinhole projection to watch the eclipse in person.

For people in the path of totality, there will be a few brief moments when it is safe to look directly at the eclipse. Only once the Moon has completely covered the Sun and there is no sunlight shining is it safe to look at the eclipse. Make sure you put your eclipse glasses back on or return to indirect viewing before the first flash of sunlight appears around the Moon’s edge.

Mira el eclipse en vivo comentado por científicas de la NASA de 10:30 a 11:30 a.m. EST el 14 de diciembre en NASA TV y la página web de la agencia.
