APOD: Full Moon, Full Mars

Image
On December 8 a full Moon and a full Mars were close, both bright and opposite the Sun in planet Earth's sky. In fact Mars was occulted, passing behind the Moon when viewed from some locations across Europe and North America. Seen from the city of Kosice in eastern Slovakia, the lunar occultation of Mars happened just before sunrise. The tantalizing spectacle was recorded in this telescopic timelapse sequence of exposures. It took about an hour for the Red Planet to disappear behind the lunar disk and then reappear as a warm-hued full Moon, the last full Moon of 2022, sank toward the western horizon. The next lunar occultation of bright planet Mars will be in the new year on January 3, when the Moon is in a waxing gibbous phase. Lunar occultations are only ever visible from a fraction of the Earth's surface, though. The January 3 occultation of Mars will be visible from parts of the South Atlantic, southern Africa, and the Indian Ocean. via NASA https://ift.tt/mkbpyBP

APOD: Comet Leonard from Space

Image
What does Comet Leonard look like from space? Today's featured image from Origin.Space's Yangwang-1 space telescope shows not only the currently bright comet -- but several other space delights as well. Taken in optical and ultraviolet light, C/2021 A1 (Leonard) is visible with an extended tail near the image center as it appeared five days ago. The Earth is visible on the lower right, while layers of the Earth's atmosphere glow diagonally from the lower left to the upper right. The trails of two satellites can be seen in front of a myriad of distant stars that dot the background on the upper left. The faint bands of light running diagonally from the lower right to the upper left are auroras. Finally, the image also caught a meteor streaking just below the airglow. To see Comet Leonard yourself from the Earth's surface during the next few days, look toward the western horizon just after sunset or just before sunrise. via NASA https://ift.tt/3s76npT

Space News: ESA awards €10.45 million to two UK launch startups

Image
by Andrew Parsonson VALLETTA, Malta — The European Space Agency awarded UK-based launch startups Orbex and Skyrora a combined €10.45 million ($12.35 million) to support development of competing microlaunchers. The two support contracts announced March 24 were awarded under Boost!, an ESA program that aims to foster new commercial space transportation services. The agency adopted Boost! during Space19+, an ESA ministerial-level council meeting held in November 2019, and announced an open call for proposals last April. Each of the two new Boost! contracts outlines specific outcomes the funding will assist the companies in achieving. Orbital Launch Express (Orbex) is developing its two-stage Prime microlauncher which is powered by 3D-printed rocket engines and is designed to carry payloads of up 150 kilograms to low Earth orbit. The vehicle is expected to make its debut in 2022. The €7.45 million in co-funding Orbex and its partners received is the largest Boost! award to date. The...

APOD:

Image
Most photographs don't adequately portray the magnificence of the Sun's corona. Seeing the corona first-hand during a total solar eclipse is unparalleled. The human eye can adapt to see coronal features and extent that average cameras usually cannot. Welcome, however, to the digital age. The featured image digitally combined short and long exposures taken in Exmouth, Australia that were processed to highlight faint and extended features in the corona during the total solar eclipse that occurred in April of 2023. Clearly visible are intricate layers and glowing caustics of an ever changing mixture of hot gas and magnetic fields in the Sun's corona. Looping prominences appear bright pink just past the Sun's edge. Images taken seconds before and after the total eclipse show glimpses of the background Sun known as Baily's Beads and diamond ring effect. The next total solar eclipse will cross North America in April of 2024. via NASA https://ift.tt/ibLzpTC

APOD: Spiral Galaxy NGC 2841

Image
A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in planet Earth's night sky toward the northern constellation of Ursa Major. This sharp image centered on the gorgeous island universe also captures spiky foreground Milky Way stars and more distant background galaxies within the same telescopic field of view. It shows off the bright nucleus of NGC 2841, along with its inclined galactic disk, and faint outer regions. Dust lanes, small star-forming regions, and young star clusters are embedded in the galaxy's patchy, tightly wound spiral arms. In contrast, many other spirals exhibit broader, sweeping arms with large star-forming regions. NGC 2841 has a diameter of over 150,000 light-years, making it even larger than our own Milky Way. X-ray images suggest that extreme outflows from giant stars and stellar explosions create plumes of hot gas extending into a halo around NGC 2841. via NASA https://ift.tt/HDshMQ9
