It’s natural to lie to yourself when you have a problem with alcohol. I know I did, in multiple ways. I lied that alcohol wasn’t actually that bad for my health even as it was clearly starting to damage my body inside and out. Then I lied to myself that “strategies” ...

Over the past 13.8 billion years, the Universe has evolved from a hot, dense, largely uniform early state to a clumpy, clustered, star-and-galaxy-rich state, where the typical interstellar and intergalactic distances are absolutely tremendous. The stars that exist today, importantly, are different f...

Red supergiants are some of the largest stars (by volume) in the Universe. Stars are not born as red giants; they become one, as this is the final stage in the evolution of most stars. Due to their massive mass, they have a short lifespan for stars — ranging from 30 million to several hundred ...

The United States is in decline. At least, according to economist Ray Dalio, who’s been studying the rise and fall of empires for most of his life. And according to many people on the street, at least according to this video by “More Perfect Union” with John Russell ...

According to the same data, 697 systems are known to include more than one planet, meaning that there is slightly more than one planet on average in planetary systems. However, this does not mean that most star systems in the galaxy have only one planet, nor does it mean that there is only one plane...

In the Universe’s youth, many galaxies experienced a period of intense star formation. Today, some galaxies, such as our own Milky Way, still form new stars, albeit not as rapidly. Other galaxies have stopped forming stars altogether. This new work can help astronomers understand the rea...

If you sit in a swivel office chair, put it around, and look at the ceiling, you will see that a spot just above your head will be fixed. It is the same with Polaris. It is just a coincidence that it is there, on our axis of rotation. The movement that gives this illusion, as I said, is...

Only 165,000 light-years distant, it’s copiously forming stars. Our Local Group of galaxies is dominated by Andromeda and the Milky Way, but there’s no denying that Andromeda is the biggest, the Milky Way is #2, Triangulum is #3, and the LMC is #4. At just 165,000 light-years away...
