A new, smaller cyclone can be seen at the lower right of this infrared image of Jupiter's south pole taken on Nov. 4, 2019, during the 23rd science pass of the planet by NASA's Juno spacecraft.

This composite visible-light image taken by the JunoCam imager aboard NASA's Juno spacecraft on Nov. 3, 2019, shows a new cyclone at Jupiter's south pole has joined five other cyclones to create a hexagonal shape around a large single cyclone.

This swirling mass of celestial gas, dust and stars is a moderately luminous spiral galaxy named ESO 021-G004, located just under 130 million light-years away.

Dorset where else eh? >>> Thats ENGLAND<<<
While it is possible for that star to go supernova(it's theorized to be due for such at any time), it's more likely to just be in a fluctuation cycle. Would be awesome to see it go off though!
Its between 450 and 600ly away and probably as a Red giant it will expand a bit more before it collapse's to turn into a Super nova
That Collapse when it happens will only take Days at most (Speculation of course).
Betelgeuse has a known recorded History of dimming and brightning and this is just probably part of its cycle
Time to worry is when it gets Significantly brighter due to Pre Nova expansion and following colapse.

PS this may allready happened :)

What making this dimming cycle remarkable and getting people excited is that it's never gone this dim since we started recording observations. Of course this can not be considered conclusive as we've not been observing it for very long. So this dimming cycle might be remarkable to us, but can be a part of a longer cycle set that cycles over a time frame of hundreds or even thousands of years.

PS this may allready happened :)

M106 (aka NGC 4258), a spiral galaxy ~ 23 million ly away has two extra spiral arms that glow in X-ray, optical and radio light. These features, or anomalous arms, are not aligned with the plane of the galaxy, but instead intersect with it.

Caldwell 33 and 34 - the large image was taken by a ground-based telescope, while the three insets are Hubble close-up views.

Galaxy NGC 3175, with its mix of bright patches of glowing gas, dark lanes of dust, bright core, and whirling, pinwheeling arms coming together, is located ~ 50 million ly away in the constellation of Antlia.

Spiral galaxy IC 2051, with its whirling, pinwheeling arms, and a bar of stars slicing through its center, lies ~ 85 million ly away in the in the southern constellation of Mensa.

This smattering of celestial sequins is a spiral galaxy named NGC 4455, located in the northern constellation of Coma Berenices. The galaxy is ~ 45 million ly away.


This Hubble Space Telescope photograph showcases the majestic spiral galaxy UGC 2885, located 232 million ly away in the northern constellation Perseus. The galaxy is 2.5 times wider than our Milky Way and contains 10 times as many stars. A number of foreground stars in our Milky Way can be seen in the image, identified by their diffraction spikes. The brightest star photobombs the galaxy's disk. The galaxy has been nicknamed "Rubin's galaxy," after astronomer Vera Rubin (1928 – 2016), who studied the galaxy's rotation rate in search of dark matter.

Located ~ 100 million ly away in the constellation of Pisces, a shell elliptical galaxy to the upper-left of this image is named NGC 474.
It is possible that the spiral galaxy to the lower-right, NGC 470, has been tugging on its larger friend for billions of years, causing density waves to reshape its structure.

Once used as the otherworldly lair for a James Bond villain, the ESO Residencia usually serves a far less sinister purpose!


This bright, somewhat blob-like object is a galaxy named NGC 1803. It is ~ 200 million ly away, in the southern constellation of Pictor.

A multitude of swirling clouds in Jupiter's dynamic 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.



Barred spiral galaxy NGC 1022



Gum 26 is located ~ 20000 ly away in the southern constellation of Vela. It is something known as an HII region or emission nebula, where the intense ultraviolet radiation streaming from newly-formed stars ionizes the surrounding hydrogen gas, causing it to emit a faint pinkish glow. By catching new stars “pink-handed” in this manner, astronomers can learn more about the conditions under which stars arise, and study how they influence their cosmic environment.

I went looking, because I'm an uneducated fool, and discovered that scientists believe approximately half of the spiral galaxies in the universe rotate clockwise, and half counter-clockwise, which was neat; however, the really cool thing is that while almost all spirals rotate with their arms trailing, interactions with other galaxies can actually cause a very few to rotate with their spirals leading the rotation :)

@Ahhzz Usually Universe doesn't care about right/left handedness (aka cosmological principle).
(Observable) Universe is homogeneous and isotropic on the (sufficiently) large scale. More interestingly, Roger Penrose is looking for concentric rings in the cosmic microwave background :)
He hopes to find them, so he can prove that there's no beginning and there's no end, just cyclical aeons. This sounds mathematically/geometrically intuitive.
Leonard Susskind is working on holographic principle. But I digress I dunno lol so many interesting ideas, we're sitting and thinking on this third planet from the sun

Unfortunately that effort will never succeed. The observations made over the year overwhelmingly show the universe expanding out from a central point in all directions. If we were to put time in reverse, everything would contract into a single point, thus effectively confirming the existence of the "big bang".

Barred spiral galaxy NGC 7541 located ~ 110 million ly away


A mega-structure assembled in a system called Abell 1758, located ~ 3 billion light-years from Earth. It contains two pairs of colliding galaxy clusters that are heading toward one another.



This image from NASA's Spitzer Space Telescope shows the Tarantula Nebula in two wavelengths of infrared light. The red regions indicate the presence of particularly hot gas, while the blue regions are interstellar dust that is similar in composition to ash from coal or wood-burning fires on Earth.

Spiral galaxy NGC 2008 located about 425 million ly from Earth in the constellation of Pictor.



This image from NASA's Spitzer Space Telescope shows the Tarantula Nebula in three wavelengths of infrared light, each represented by a different color.
The green color in this image shows the presence of particularly hot gas emitting infrared light at a wavelength of 4.5 micrometers. The stars in the image are mostly a combination of green and blue. White hues indicate regions that radiate in all three wavelengths.

Jupiter's Equator



Thick white clouds are present in this JunoCam image of Jupiter's equatorial zone. These clouds complicate the interpretation of infrared measurements of water. At microwave frequencies, the same clouds are transparent, allowing Juno's Microwave Radiometer to measure water deep into Jupiter's atmosphere.
