Black_Hole-M_87.jpgBlack Hole in the "Heart" of M 87170 visiteThe jets emanating from a famous Black Hole are cruising along at about 99% the speed of light, according to observations from NASA's Chandra X-Ray Observatory.
Researchers spotted the speedy jets emanating from a Black Hole in the galaxy Messier 87 — the same Black Hole that was imaged directly for the first time by the Event Horizon Telescope.
In this wide-field image of Messier 87 from the Chandra X-ray Observatory, the white box indicates the approximate location of the black hole's jet.MareKromiumMag 20, 2020

Black_Hole-BB13U1YE.jpgBlack Hole in the "Heart" of M 87184 visiteThe first image of a black hole, previously thought nigh impossible to capture, was named the top scientific breakthrough of 2019 by the journal "Science".
Black holes have gravitational pulls so powerful that, past thresholds known as their event horizons, nothing can escape, not even light. Supermassive black holes millions to billions of times the mass of our sun are thought to lurk in the hearts of virtually every large galaxy, influencing the fate of every star caught in their gravitational thrall.
Using Albert Einstein's theory of general relativity, German physicist Karl Schwarzschild was the first to lay the foundation of the science describing black holes. In the decades since then, scientists have detected numerous signs of black holes, such as the effects their gravity have on their surroundings and the ripples in the fabric of space and time known as gravitational waves emitted when they collide.MareKromiumMag 20, 2020

101955-Bennu-011.png101955 Bennu - Just like Itokawa (Natural Colors; credits for the additional process. and color.: E. Bonora & Marco Faccin)217 visiteNotate la posizione "anomala" e "sporgente" dei mega-boulders (mega-macigni) visibili. Bizzarro, vero?!? La "causa" della nascita di 101955 Bennu? Aggregazione Gravitazionale di detriti. Così come Itokawa. Asteroidi fragili, polverosi e senza crateri. Ere di "lavoro" (miliardi di anni terrestri) e questo ne é un (altro esempio di) risultato.MareKromiumApr 15, 2020

Jupiter-PIA22948.jpgJupiter Abyss...186 visiteCaption NASA Originale:"NASA's Juno spacecraft captured this view of an area within a Jovian jet stream showing a vortex that has an intensely dark center. Nearby, other features display bright, high altitude clouds that have puffed up into the sunlight.
The color-enhanced image was taken at 12:55 a.m. PDT (3:55 a.m. EDT) on May 29, 2019, as the spacecraft performed its 20th science fly-by of Jupiter. At the time, Juno was about 9.200 miles (approx. 14.805,96 Km) from the Planet's cloud tops, above approximately 52° North Latitude.
Citizen scientists Gerald Eichstädt and Seán Doran created and named this image using data from the spacecraft's JunoCam imager".MareKromiumApr 04, 2020

Jupiter-White_Storm-PIA23445.jpgWhite Storm on Jupiter148 visiteCaption NASA Originale:"This view of Jupiter's Upper Atmosphere from NASA's Juno Spacecraft includes something remarkable: two storms caught in the act of merging.
The two white ovals seen within the orange-colored band left of center are Anticyclonic Storms — that is, storms that rotate counter-clockwise. The larger of the two ovals has been tracked for many years, as it grew in size through mergers with other Anticyclonic white ovals.
JunoCam was fortunate to capture this new merger, which typically takes place over the course of only a few days.
The event interests scientists because the ovals had approached each other months earlier, only to move apart again.
This merger may be the result of perturbations due to the proximity of Oval BA, which is the larger storm just to the North of the two merging, white ovals. Oval BA is the second largest Anticyclonic Vortex in Jupiter's Atmosphere (second only to the famous Great Red Spot). During this pass over Jupiter, Juno gave scientists their best views of Oval BA to date.
Citizen scientist Tanya Oleksuik created this color-enhanced image using data from the JunoCam camera. The original image was taken on December, 26, 2019, at 10:28 a.m. PST (1:28 p.m. EST) as the Juno Spacecraft performed its 24th close fly-by of the Planet. At the time, the Spacecraft was about 44.900 miles (such as approx. 72.259,54 Km) from the tops of Jupiter's clouds, at a latitude of about 60° South".MareKromiumApr 04, 2020

Europa-PIA23166.jpgRhadamanthys Linea (Enhanced Natural Color Version)139 visiteCaption NASA Originale:"Europa's Surface is covered with a vast network of Linear Features such as cracks, ridges, and bands, as well as other smaller circular features that include pits, spots, domes, and microchaos.
This image, created from clear-filter images taken on the Galileo spacecraft's 17th orbit around Jupiter and colorized with lower-resolution images taken on Galileo's first orbit around Jupiter, shows a huge variety of these feature types.
Of particular note is the prominent ridge at the center of the image, called Rhadamanthys Linea.
While most ridges have a reddish appearance in colorized images such as this enhanced color version, Rhadamanthys appears to have uneven blotches of darker, redder material which are more prominent in some locations than in others.
Some scientists have interpreted the appearance of Rhadamanthys to indicate that it is a recently, or perhaps currently, active feature on Europa's Surface".MareKromiumApr 04, 2020
