Do you think it’s possible that Pluto is an escaped moon of Neptune, and if not, why not? The opinions I can find on the matter leave me a bit confused.
Well, first of all I’m not an expert and my explanation may be wrong. I’ve heard of it, but it seems that hypothesis is not very likely. If pluto has orbited Neptune before, it would have to have a phenomenon with an extremely large energy so that Pluto would leave the Neptunian orbit and manage to escape.
Although at some point the orbits of Pluto and Neptune “ get close ”, it is still far enough away that they do not interact, and Pluto has an inclined orbit compared to Neptune. These factors make it even more difficult.
This month, in honor of Valentine’s Day, we’ll focus on celestial star pairs and constellation couples.
Let’s look at some celestial pairs!
The constellations Perseus and Andromeda are easy to see high overhead this month.
According to lore, the warrior Perseus spotted a beautiful woman–Andromeda–chained to a seaside rock. After battling a sea serpent, he rescued her.
As a reward, her parents Cepheus and Cassiopeia allowed Perseus to marry Andromeda.
The great hunter Orion fell in love with seven sisters, the Pleiades, and pursued them for a long time. Eventually Zeus turned both Orion and the Pleiades into stars.
Orion is easy to find. Draw an imaginary line through his belt stars to the Pleiades, and watch him chase them across the sky forever.
A pair of star clusters is visible on February nights. The Perseus Double Cluster is high in the sky near Andromeda’s parents Cepheus and Cassiopeia.
Through binoculars you can see dozens of stars in each cluster. Actually, there are more than 300 blue-white supergiant stars in each of the clusters.
There are some colorful star pairs, some visible just by looking up and some requiring a telescope. Gemini’s twins, the brothers Pollux and Castor, are easy to see without aid.
Orion’s westernmost, or right, knee, Rigel, has a faint companion. The companion, Rigel B, is 500 times fainter than the super-giant Rigel and is visible only with a telescope.
Orion’s westernmost belt star, Mintaka, has a pretty companion. You’ll need a telescope.
Finally, the moon pairs up with the Pleiades on the 22nd and with Pollux and Castor on the 26th.

Tried to look at stars through my window however couldn't see anything I blame British weather, while my neighbour hid in my bed because it was cold
Happy Earth day! (Let’s take care of our planet while there’s time)

Hi, I’m here now. A friend convinced me to start so lets see how bad I fail XD
The Large Hadron Collider (LHC) is the world’s largest and most powerful particle collider, the most complex experimental facility ever built, and the largest single machine in the world. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories. It lies in a tunnel 27 kilometres (17 mi) in circumference, as deep as 175 metres (574 ft) beneath the France–Switzerland border near Geneva.
The aim of the LHC is to allow physicists to test the predictions of different theories of particle physics, including measuring the properties of the Higgs boson and searching for the large family of new particles predicted by supersymmetric theories, as well as other unsolved questions of physics.
All the controls for the accelerator, its services and technical infrastructure are housed under one roof at the CERN Control Centre. From here, the beams inside the LHC are made to collide at four locations around the accelerator ring, corresponding to the positions of four particle detectors – ATLAS, CMS, ALICE and LHCb.

I enjoy telescopes too much for my own good. (PS. my header is fireworks because nothing else fits yet)
