Space Science News Thread

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

This is not the same as Science news. This thread is for the latest findings in Space Science, which includes Astronomy, Astrophysics and Heliophysics, and Planetary Sciences. This includes articles about Asteroids, Comets, Exoplanets, and Stars in other Solar Systems.

For example:

Unusual spiral quasar seen dancing with a companion

Are quasars the BH’s galaxy or the BH itself? Or both?

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

To my knowledge, Quasars are the “active” Black Holes in the center of their respective Galaxies. I think sometimes Astrophysicists and Astronomers refer to Galaxies with Quasars as Quasar Galaxies.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

I guess so, but at times I’ve heard the galaxies themselves being reffered to as quasars…

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

Maybe all three uses are correct? At least term usage isn’t as confusing as in Geology (nothing against Geologists).

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Why is the term usage in geology considered so confusing amongst the various sciences?

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

I think the usage isn’t as standardized compared to other scientific fields, but I am no 100% sure if that is the reason for it.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

I’d think there do exist not-so-well standardized fields of science, but I didn’t think the rather well-established geology could be one of them…

Black holes are spinning faster than expected, researchers find

[nightvampalihan]

lol one day they will came with it that it was all random calculations and everything was wrong

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

I mean, we can never truly know, but we can have the most likely idea as a candidate for what’s really happening…

[MeghalayanAge (AnthropocenianAge's Alt.)]

The rover Perseverance took the first pictures of a Martian Aurora.

Perseverance takes the first picture of a visible Martian aurora

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

I thought mars couldn’t have these considering lack of a magnetic field?

[MeghalayanAge (AnthropocenianAge's Alt.)]

Auroras occur when charged particles from a star or space interact with a planet’s atmosphere. Magnetic fields are not essential for Auroras to occur. In planets or moons with magnetic fields and atmospheres, auroras occur on their respective North and South pole regions, since the charged particles are funneled there by the magnetic fields.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

So I suppose mars has them over their whole surface at times…

[MeghalayanAge (AnthropocenianAge's Alt.)]

Scientists did not think Auroras in the visible spectrum occurred on Mars until Perseverance took a picture of it. So, yes, Auroras probably occur all over Mars, if we can see them.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

There are also apparently large auroras on gas giant planets iirc

[MeghalayanAge (AnthropocenianAge's Alt.)]

Do Auroras take place on the Sun?

Yup. They can.

Astronomers spot aurora on the sun for the 1st time

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Next up, auroras around black holes.
