NASA to launch a “relatively low cost Mars mission” on Blue Origin’s New Glenn rocket’s first launch… seems like a dodgy investment for an unproven rocket.
Meet Amaterasu! Highest energy cosmic ray since the Oh-My-God ray in 1991. It seems that the universe's mysteries are endless. The question is: unknown natural phenomenon or.... drum roll alienzzzz?

If it came from the dark zone just outside the Milky Way, there is a possibility it has something to do with dark energy or dark matter… but as the researcher said, we are just spitballing ideas because we just don’t know, it’s a real mystery.

The Hubble Space Telescope might be getting on in years, but it's still making important observations. Astronomers have turned the iconic space telescope toward one of our nearest neighbors, a star system called LTT 1445 that's home to the nearest transiting exoplanet. Hubble has confirmed previous findings that this is a small, rocky world. More than that, Hubble determined that it's almost exactly the size of Earth and is just 22 light-years away.
Amateur astronomy societies, which exist everywhere, often organise public star parties. The cool thing about them is that you get to observe through many different sizes and types of telescopes and get to ask any question you might have. Just an idea.

As we have learned more about the cosmos, it has become clear planets are not rare. Astronomers have confirmed thousands of exoplanets, and we're finally beginning to spot some solar systems with large collections of planets not unlike ours. You can add HD 110067 to that list, as an international team has detected six gas giants orbiting this star. The number of exoplanets by itself would make HD 110067 worthy of further study, but there's more—these planets orbit in a rare gravitational resonance that may have been repeating for billions of years.
Never stop looking up. They are always watching in amazement at us humans.

I'm not totally up on the findings, but from what I've heard is that the headlines about disproving the Big Bang are sensationalized and very premature.

It seems some “alternative thinkers” got hold of the data and started saying it supported their personal pet theories and that went viral. The Big Think article was cooler heads talking about the end result.

That's a wonderful image @Jeroen. I am constantly amazed at what amateur imagers can do these days. They can certainly make better images than the professionals 40 years ago, and maybe even 20 years ago. Insane!

“One consequence of a supernova is the production of galactic winds, which play a key role in regulating star formation. Although galactic winds have already been observed in several nearby galaxies, a team of scientists has now made the first direct observations of this phenomenon in a large population of galaxies in the distant Universe, at a time when galaxies are in their early stages of formation.”
Betelgeuse is considered by astronomers to be one of the stars that will go supernova very soon in cosmic time, maybe even during our lifetimes.
Betelgeuse is the upper-left bright star in Orion and is one of the brightest stars in the sky. It is also called Alpha Orionis, which means it is the brightest (Alpha) star in the constellation Orion.
My previous readings said it would explode within 1000 years, or 100,000 years, but this article says it might be even sooner, within 300 years.
_Life on Earth will be unharmed. But that doesn’t mean it will go unnoticed. Goldberg and Bauer found that when Betelgeuse explodes, it will shine as bright as the half-Moon — nine times fainter than the full Moon — for more than three months.
“All this brightness would be concentrated into one point,” Howell says. “So it would be this incredibly intense beacon in the sky that would cast shadows at night, and that you could see during the daytime. Everyone all over the world would be curious about it, because it would be unavoidable.”

“The discovery of so-called "odd radio circles" several years ago had astronomers scrambling to find an explanation for these enormous regions of radio waves so far-reaching that they have galaxies at their centers. Scientists at the University of California, San Diego, think they have found the answer: outflowing galactic winds from exploding stars in so-called "starburst" galaxies. They described their findings in a new paper published in the journal Nature.
“These galaxies are really interesting,” said Alison Coil of the University of California, San Diego. “They occur when two big galaxies collide. The merger pushes all the gas into a very small region, which causes an intense burst of star formation. Massive stars burn out quickly, and when they die, they expel their gas as outflowing winds.”
There was an article that stated that when the Milky Way and Andromeda galaxies collide, the space between stars is so vast that there will be few actual collisions. The big effect is the relative gravitational pull that will greatly change both galaxies. They may ultimately merge with small clusters spinning off and/or one will take possession of a large galactic portion from the other.
There, according to reported indices, are signs that the collision process has already begun. While the to galaxies are still approx, 2.5 million light years apart, it was reported that we may be sharing gravitational effects. As to the voracity of those claims, I leave that to the Astronomers and Astro Physicyts.
Meanwhile, pleasant as these little excursions are, I'll be tending to the mini galaxy within my own minor sub-sub quadrant of Earth.
Peace to All

By the way… did you know that the iPhone has a pretty cool “astronomy” backdrop for the Lock Screen and Home Screen, where by default you get a view of the Earth from space showing your location with accurate lighting by the sun and day-night patterns on the globe?
And I just discovered that if you go and adjust this in the Settings, you can switch the view to any other planet in the solar system? I’ve been rocking a view of Neptune on my Lock Screen for the last few days.

I think the analogy I remember regarding the collision of galaxies and the vast space in them, is like if two bees roaming through Europe or the US were to collide into each other.
