It spans the sky like a mega-size wad of chewing gum stretched taut. It glows from within, pulses gently and sometimes releases tentacles of dripping, green ectoplasm.

Historic encounters with the asteroid Bennu and the Kuiper belt object MU69 have revealed strange new features of these far-flung worlds.

A supermoon — which typically happens two to three times per year — is a full moon that occurs at the moon’s perigee, the point in the moon’s orbit when it is closest to the earth, making it appear bigger and brighter in the sky. Because the moon’s orbit is shaped more like an egg, as opposed to a perfect circle. (Conversely, the apogee is the point when the moon is farthest from earth.)..it is relatively rare for a supermoon to coincide with the Spring Equinox. The last time the cosmic alignment happened was in 2000, and it won’t occur again until 2038.The “super worm moon” is the last supermoon of 2019. The next supermoons are set to light up the skies on March 9 and April 8, 2020.

Meteorologist Matt Brickman says the first day of astrological spring in Minnesota will be breezy, cloudy, with average highs in the low-to-mid 40s.

Scientists at a conference in Houston presented the concept for a flyby mission to study a mysterious moon that may contain an ocean.

NASA’s Osiris-Rex and Japan’s Hayabusa2 spacecraft reached the space rocks they are surveying last year, and scientists from both teams announced early findings on Tuesday.

all the pulsars!

> The bulk composition of Bennu appears to be hydrated and volatile-rich, as expected. However, in contrast to pre-encounter modelling of Bennu’s thermal inertia12 and radar polarization ratios13—which indicated a generally smooth surface covered by centimetre-scale particles—resolved imaging reveals an unexpected surficial diversity. The albedo, texture, particle size and roughness are beyond the spacecraft design specifications. On the basis of our pre-encounter knowledge, we developed a sampling strategy to target 50-metre-diameter patches of loose regolith with grain sizes smaller than two centimetres4. We observe only a small number of apparently hazard-free regions, of the order of 5 to 20 metres in extent, the sampling of which poses a substantial challenge to mission success.

Explanation: This bright cosmic cloud was sculpted by stellar winds and radiation from the hot young stars of open cluster NGC 3324. With dust clouds in silhouette against its glowing atomic gas, the pocket-shaped star-forming region actually spans about 35 light-years. It lies some 7,500 light-years away toward the nebula rich southern constellation Carina. A composite of narrowband image data, the telescopic view captures the characteristic emission from ionized sulfur, hydrogen, and oxygen atoms mapped to red, green, and blue hues in the popular Hubble Palette. For some, the celestial landscape of bright ridges of emission bordered by cool, obscuring dust along the right side create a recognizable face in profile. The region's popular name is the Gabriela Mistral Nebula for the Nobel Prize winning Chilean poet.

This guide will be a walkthrough on the basics of Milky Way photography. It is best for beginners, but even intermediate and expert photographers might find something new! Plus, I always find it never hurts to refresh yourself on the basics.
Before we get to the good stuff, I’d like to start by saying that I hope you find this guide to be a bit different from the rest. I have found that most guides go on way too long and provide more detail than you could possibly need. This doesn’t sound like a bad thing, but it creates a problem. With that much information available, it tends to be overwhelming and hard to retain what you learn. By the time you’ve read through the countless pages, you’ve forgotten where you started!
The goal of this guide is to get you through the basics as quickly as possible so you can get out shooting! Think of this guide as the notes you would take during a lecture. When you start out, learning only the most important basics gives you more time to take photos of the Milky Way, which is by far the quickest way to learn and improve your art.

Explanation: Big, beautiful spiral galaxy M101 is one of the last entries in Charles Messier's famous catalog, but definitely not one of the least. About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way galaxy. M101 was also one of the original spiral nebulae observed by Lord Rosse's large 19th century telescope, the Leviathan of Parsontown. M101 shares this modern telescopic field of view with more distant background galaxies, foreground stars within the Milky Way, and a companion dwarf galaxy NGC 5474 (lower right). The colors of the Milky Way stars can also be found in the starlight from the large island universe. Its core is dominated by light from cool yellowish stars. Along its grand design spiral arms are the blue colors of hotter, young stars mixed with obscuring dust lanes and pinkish star forming regions. Also known as the Pinwheel Galaxy, M101 lies within the boundaries of the northern constellation Ursa Major, about 23 million light-years away. Its companion NGC 5474 has likely been distorted by its past gravitational interactions with the dominant M101.
