.. ajustando algunas ESTRELLAS DE 1era MAGNITUD ..


A multitude of magnificent, swirling clouds in Jupiter's dynamic North North Temperate Belt is captured in this image from NASA's Juno spacecraft. Appearing in the scene are several bright-white “pop-up” clouds as well as an anticyclonic storm, known as a white oval.

This color-enhanced image was taken at 1:58 p.m. PDT on Oct. 29, 2018 (4:58 p.m. EDT) as the spacecraft performed its 16th close flyby of Jupiter. At the time, Juno was about 4,400 miles (7,000 kilometers) from the planet's cloud tops, at a latitude of approximately 40 degrees north.

Citizen scientists Gerald Eichstädt and Seán Doran created this image using data from the spacecraft's JunoCam imager.

JunoCam's raw images are available for the public to peruse and to process into image products at:

THE LAGOON NEBULA IS STARS, GAS, AND DUST Image Credit & Copyright: Nelson Ortega

Explanation: The majestic Lagoon Nebula is filled with hot gas and the home for many young stars. Spanning 100 light years across while lying only about 5000 light years distant, the Lagoon Nebula is so big and bright that it can be seen without a telescope toward the constellation of the Archer (Sagittarius). Many bright stars are visible from NGC 6530, an open cluster that formed in the nebula only several million years ago. The greater nebula, also known as M8 and NGC 6523, is named "Lagoon" for the band of dust seen to the left of the open cluster's center. The featured image was taken in three colors with details are brought out by light emitted by Hydrogen Star formation continues in the Lagoon Nebula as witnessed by the many dark dust-laden globules that exist there.

What would it be like to explore the Moon? NASA's Apollo missions gave humans just this chance in the late 1960s and early 1970s. In particular, the Apollo 15 mission was dedicated to better understanding the surface of the Moon by exploring mountains, valleys, maria, and highlands. Astronauts David Scott and James Irwin spent nearly three days on the Moon while Alfred Worden orbited above in the Command Module. The mission, which blasted off from Earth on 1971 July 26, was the first to deploy a Lunar Roving Vehicle. Pictured in this digitally stitched mosaic panorama, David Scott, exploring his surroundings, examines a boulder in front of the summit of Mt. Hadley Delta. The shadow of James Irwin is visible to the right, while scrolling to the right will reveal a well-lit and diverse lunar terrain. The Apollo 15 mission returned about 76 kilograms of moon rocks for detailed study. In the future, NASA and other space agencies plan to continue to lead humanity's exploration of the Moon, Mars, and beyond.

THE OLD MOON IN THE YOUNG MOON'S ARMS Image Credit & Copyright: Stan Honda

Tonight the Moon is young again, but this stunning image of a young Moon near the western horizon was taken just after sunset on October 10. On the lunar disk Earthshine, earthlight reflected from the Moon's night side, is embraced by the slim, sunlit crescent just over 2 days old. Along the horizon fading colors of twilight silhouette the radio telescope dish antennas of the Very Large Array, New Mexico, planet Earth. The view from the Moon would be stunning, too. When the Moon appears in Earth's sky as a slender crescent, a dazzlingly bright, nearly full Earth would be seen from the lunar surface. A description of earthshine, in terms of sunlight reflected by Earth's oceans in turn illuminating the Moon's dark surface, was written 500 years ago by Leonardo da Vinci.

Parker Solar Probe is alive and well after skimming by the Sun at just 15 million miles from our star's surface. This is far closer than any spacecraft has ever gone — the previous record was set by Helios B in 1976 and broken by Parker on Oct. 29 — and this maneuver has exposed the spacecraft to intense heat and solar radiation in a complex solar wind environment.

“Parker Solar Probe was designed to take care of itself and its precious payload during this close approach, with no control from us on Earth — and now we know it succeeded,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate at the agency headquarters in Washington. “Parker is the culmination of six decades of scientific progress. Now, we have realized humanity’s first close visit to our star, which will have implications not just here on Earth, but for a deeper understanding of our universe.”

Mission controllers at the Johns Hopkins University Applied Physics Lab received the status beacon from the spacecraft at 4:46 p.m. EST on Nov. 7, 2018. The beacon indicates status "A" — the best of all four possible status signals, meaning that Parker Solar Probe is operating well with all instruments running and collecting science data and, if there were any minor issues, they were resolved autonomously by the spacecraft.

At its closest approach on Nov. 5, called perihelion, Parker Solar Probe reached a top speed of 213,200 miles per hour, setting a new record for spacecraft speed. Along with new records for the closest approach to the Sun, Parker Solar Probe will repeatedly break its own speed record as its orbit draws closer to the star and the spacecraft travels faster and faster at perihelion.

On Nov. 5, 2018, Parker Solar Probe achieved its first close approach to the Sun, called perihelion, a maneuver that exposed the spacecraft to intense heat and solar radiation.

At this distance, the intense sunlight heated the Sun-facing side of Parker Solar Probe's heat shield, called the Thermal Protection System, to about 820 degrees Fahrenheit. This temperature will climb up to 2,500 F as the spacecraft makes closer approaches to the Sun — but all the while, the spacecraft instruments and systems that are protected by the heat shield are generally kept in the mid-80s F.

Parker Solar Probe's first solar encounter phase began on Oct. 31, and the spacecraft will continue collecting science data through the end of the solar encounter phase on Nov. 11. It will be several weeks after the end of the solar encounter phase before the science data begins downlinking to Earth.

SUN PILLAR Taken by Lauri Kangas on November 4, 2018 @ Fort Frances, Ontario, Canada

On the evening of Nov 4th there was a colourful sunset and a sun pillar slowly appeared. The skies were particularly interesting due to the orange clouds and the clear areas of turquoise sky. Orange and blue are complementary colours and contrast well with each other. Photos taken with a Canon 6D DSLR.
