What if The Heart of The Milky Way Isn't Actually a Black Hole Like We Thought?
We sort-of take it for granted that there's a supermassive black hole at the center of the Milky Way galaxy, but we can't really go there and check. What if something else is actually lurking in this messy, dusty region?
We partially infer the presence and properties of a supermassive hole called Sagittarius A* (Sgr A*) from the gravitational effect it has on other objects, like the extreme orbits of objects like stars around that galactic center… but what if we're wrong?

See Those Colorful Balls? Yeah, They're All Actually Beige
These levitating spheres may appear red, purple or green at first glance, but in actuality, all 12 orbs are the same bland shade of beige.
But why do we perceive the spheres as anything but their true color?

The First Clinical Trial For Cannabis as a Migraine Treatment Is Underway
Cannabis has been used to relieve headaches for thousands of years, and yet rigorous clinical trials on this ancient remedy for head pain have only just begun.
The first double-blind, randomized, placebo-controlled study is now investigating whether cannabis products, like THC and CBD, can actually treat acute migraines in a safe and effective way...

Hatching planets
A Hubble Space Telescope view of a small portion of the Orion Nebula reveals five young stars. Four of the stars are surrounded by gas and dust trapped as the stars formed, but were left in orbit about the star. These are possibly protoplanetary disks, or 'proplyds', that might evolve on to agglomerate planets.

The Oldest Known Spiral Galaxy Was Just Detected, And It Has Some Surprises For Us
Scientists have captured a picture of the oldest known spiral galaxy, which was formed 12.4 billion years ago.
The Jellyfish and Mars
Normally faint and elusive, the Jellyfish Nebula is caught in this alluring scene. It floats below and left of center, a bright arcing ridge of emission with dangling tentacles. In fact, the cosmic jellyfish is part of bubble-shaped supernova remnant IC 443, the expanding debris cloud from a massive star that exploded. Light from that explosion first reached planet Earth over 30,000 years ago.
Like its cousin in astrophysical waters the Crab Nebula supernova remnant, the Jellyfish Nebula is known to harbor a neutron star, the remnant of the collapsed stellar core. This telescopic snapshot also captures Mars. Now wandering through early evening skies, the Red Planet also shines with a yellowish glow on the right hand side of the field of view.
The Jellyfish Nebula is about 5,000 light-years away, while Mars is currently almost 18 light-minutes from Earth.

We've Tracked 5 Mysterious Fast Radio Bursts to The Arms of Distant Spiral Galaxies
The mystery of fast radio bursts (FRBs) continues to fascinate astronomers. No one is quite sure what's behind these super-short, super-intense radio wave pulses from deep space, but now astronomers have tracked down five FRBs to their home galaxies.
It's the Hubble Space Telescope that has come up with the goods again. The ultraviolet and infrared cameras on the telescope were used to see where on a star map these five bursts emerged from, which gives us a better understanding of how they might have come into being in the first place...

The Nostalgia Effect
From where we were, to where we are, to where we will be, nostalgia will be there all along the way.
It’s the burning desire to go back to the past, live the life we once had, or perhaps only a romanticized version of it. We want experiences, places, things, people, and even ourselves to go back to being what they once were...

Dogs Can Detect Over 90% of COVID-19 Cases, Even Asymptomatic Ones
Dogs can be trained to detect more than 90 percent of COVID-19 infections even when patients are asymptomatic, according to new research available in preprint, which authors hope could help replace the need to quarantine new arrivals.
Using their remarkable sense of smell - which can pick up the equivalent of half a teaspoon of sugar in an Olympic-sized swimming pool - dogs have already shown that they can sniff out maladies such as cancer, malaria and epilepsy.

How Exactly Do Planetary Flybys Work?
Gravity assists, sometimes called flybys, are a big part of space exploration. These precision maneuvers involve harnessing a planet’s gravity to accelerate and direct a spacecraft to some far-flung destination so the spacecraft can go further without a big and heavy propulsion system. It’s a key element in both human and robotic space explotration...

Gene Therapy Partially Restores Vision in Blind Patient in First Case of Its Kind
A blind man who lost his sight to a neurodegenerative eye disease decades ago has had his vision partially restored, thanks to a first-of-its-kind experimental gene therapy.
For those people and their families, recent advancements in optogenetics could be a source of new hope for restored vision – although it's worth emphasizing this approach is still very much in the experimental stage, with practical treatments likely to be years away....

Scientists Discover a New Type of Biochemical That Could Be in All Life on Earth
The wonderful mess of molecules that make up living things is so complex, biologists have overlooked an entire class of them – until now. This missed bit of biochemistry is neither rare nor hard to find; it's just no one had thought to look for it before.
"This is a stunning discovery of an entirely new class of biomolecules," said Carolyn Bertozzi. "It's really a bombshell because the discovery suggests that there are biomolecular pathways in the cell that are completely unknown to us."

In the Blink of an Eye: Space in an Instant
When we look up at night, the universe seems pretty quiet. But that perspective is an illusion; in reality, there are millions of world-shattering events happening every instant across the cosmos. This short film explores just how much is going on every moment in our ridiculously enormous universe.
In the fraction of a second it takes to blink your eyes, thousands of stars will be born, hundreds will explode and die, millions of planets will form, and our universe will expand by half a million kilometers in diameter.
And these numbers only account for the observable universe -- not for what could be happening beyond, where some scientists believe there could be an infinite expanse of space.
Think next time you blink.

What Are You Doing With Your Life? The Tail End
Wrapping your mind around your life is pretty hard, because you are up to your neck in it. It's like trying to understand the ocean while learning how to swim. On most days you are busy just keeping your head above water. So it is not easy to figure out what to do with your life and how to spend your time.
It’s easy to get lost. So let us take a step back and take a look at your life from the outside.
