Mars: Many Fantastic Colors [Video] | NASA MRO
Colorful terrain on Mars surface with exposed bedrock
The Nili Fossae region, located on the northwest rim of Isidis impact basin, is one of the most colorful regions of Mars. The colors over many regions of Mars are homogenized by the dust and regolith, but here the bedrock is very well exposed, except where there are sand dunes. The rocks also have diverse compositions. This region is ancient and has had a complicated geologic history, leading to interesting structures like layered bedrock, as well as other compositions.

These images of Nili Fossae were taken on Feb. 5, 2016, at 14:54 local Mars time by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.

Southern Skies

Only about 10% of the world's population gets an opportunity to see the Southern Skies looking up, as they do, from the Southern Hemisphere. So when reddit user, u/inefekt posted a picture of the Milky Way from Australia u/youreeka decided to create an educational documentary on what the rest of us are missing.

    ● Galactic Centre: Supermassive black hole at the centre of the Milky Way (26,000ly)   
    ● Great Rift: Giant dust cloud floating through Milky Way (300ly)   
    ● Southern Cross: Includes Gamma Crucis, closest red giant (100x larger than the Sun) at the top (88ly)   
    ● Coalsack Nebula: Dark nebula and head of the dark constellation Emu in the Sky (Australian Aboriginal Astronomy)
    ● Alpha Centauri: Closest star system to the Sun, trinary star system (4.2ly) 
    ● Large Magellanic Cloud: Dwarf Galaxy orbiting the Milky Way (160,000ly)   
    ● Small Magellanic Cloud: Dwarf Galaxy orbiting the Milky Way (200,000ly)  
    ● 47 Tucanae: Globular Star Cluster (16,700ly)  
    ● Tarantula Nebula: Nebula within LMC   
    ● Canopus: Second brightest star (300ly)   
    ● Eta Car: Exploded star system (7,500ly)   
    ● Antares: Red supergiant (1000x larger than the Sun) (550ly)   
    ● Mars: 4th closest planet to the Sun (150 million km away in this image)
    ● Saturn: Gas giant, 6th closest planet to the Sun with a ring system made of iced water.

Awesomely beautiful.. I look up to the sky every night just to feel inspired that we're a small part of such beauty.

¿Cómo de grande es nuestro Sol si lo comparamos a otras estrellas?
En este espectacular y popular video de YouTube, se nos muestran los tamaños relativos de los planetas y las estrellas de pequeño a más grande.
El video empieza con la Luna Terrestre y progresa hacia los planetas más grandes del Sistema Solar.
Luego, el Sol va comparándose con otras brillantes estrellas del vecindario de la Vía Láctea.
Finalmente, aparecen en plano algunas de las estrellas más grandes conocidas.
Nótese que el verdadero tamaño de la mayoría de las estrellas fuera del Sol y Betelgeuse no son conocidos por observación directa, sino por mediciones de su brillo, temperatura, y distancia.
Aunque sea una herramienta de aprendizaje inspiradora casi precisa, animamos a los lectores de Observatorio a completar dicha experiencia (y quizá a hacer futuras versiones más precisas) y que citen pequeñas incongruencias en el video.

Solar flares are immensely powerful events on the Sun. They are X-ray bursts which are connected to what very often become the largest explosions in the solar system.

We have built a fleet of satellites to investigate everything happening on the one star we can observe from close at hand.

Did you know the Sun had a pulse?

Dette er Tarjei Antonsen, hoveddesigneren og utviklingssjef for et instrument som skal skytes over von-Karman linjen (100 km) i sommer. Instrumentet skal undersøke nattlysende skyer og meteorittpartiklene de består av.

Her forklarer han litt mer om hvordan det går an å undersøke grenseområdet mellom jordas atmosfære og verdensrommet.

Spoiler Alert: Det har med raketter å gjøre. ;)

 It is an epic camera, the zoom is crazy lol. I think I shot this handheld so I will try to get better quality using a tripod next time.

A tan solo 20 años luz en dirección a la constelación de Libra, la estrella enana roja Gliese 581 ha sido objeto de mucho escrutinio por los astrónomos en estos años. Telescopios con base en tierra han detectado la firma de múltiples planetas orbitando ese frío sol, con al menos dos de ellos cercanos a la zona habitable del sistema: la región donde un planeta similar a la Tierra puede tener agua líquida en su superficie.
Ahora un equipo encabezado por Steven Vogt (UCO Lick), y Paul Butler (DTM Carnagie Inst.) ha anunciado la detección de otro planeta, este claramente en la zona habitable del sistema. Basado en 11 años de datos, su trabajo ofrece un evidente caso del primer planeta encontrado potencialmente habitable en torno a una estrella muy próxima.
Mostrado en esta ilustración artística de la parte interior del sistema exoplanetario, el planeta se ha denominado Gliese 581g, pero el nombre más personal para Vogt es el mundo de Zarmina, en honor a su esposa.
El mejor ajuste a los datos indica que el planeta tiene una órbita circular de 37 días, un radio orbital de tan solo 0,15 UA , y una masa 3,1 veces la terrestre. El modelo incluye estimaciones de un radio del planeta de 1,5, y una gravedad en superficie de 1,1 a 1,7, en unidades Terrestres.
El encontrar un planeta habitable tan cercano sugiere que hay muchos más en nuestra Galaxia, la Vía Láctea.

Catching a Cluster of Stars

Click on the image for animation
While NASA's Cassini spacecraft was pointed to study Saturn's F ring, it happened to catch a globular star cluster passing through the camera's field of view.
This movie is a concatenation of 13 images each taken about three minutes apart that show NGC 5139, or Omega Centauri. Some of the cluster's stars can even be seen through the ring's narrow Keeler Gap near the end of the movie. The cluster was in Ptolemy's star catalogue but was officially discovered by Edmond Halley in 1677 and was recognized as a globular cluster by John Herschel.
This view looks toward the northern, unilluminated side of the rings from about 53 degrees above the ring plane. The stars on average were brightened by a factor of 10 relative to Saturn's rings. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 29, 2009. The view was acquired at a distance of approximately 1.2 million kilometers (746,000 miles) from Saturn and at a sun-Saturn-spacecraft, or phase, angle of 57 degrees. Image scale is 7 kilometers (4 miles) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
