From 10 billion years ago, a cluster more than 500 trillion times the Sun’s mass is revealed to us. “If you take a galaxy and try to make it bigger, […]

And if it is, what does that mean for dark energy, and our Universe’s fate? “Until the 1990s, there were few reliable observations about movement at the scale of the […]
The search for Planet Nine is on. The problem is scientists don’t know where to start — it has an orbit of 10,000 to 20,000 years. However, a group of researchers from France may have narrowed the search area.
Who knows what we’ll see. We may be able to witness the beginning of everything.
How colliding galaxy clusters emit the most spectacular fireworks, if only you look beyond what your eyes can see! “Every single time you make a merger, somebody is losing his identity. […]
The stars, gas, nebulae and dust in our galactic plane make it impossible to see through. But there are other forms of light. “Vision is the art of seeing what is […]
And how close does the farthest one we’ve ever found so far come to it? “Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics […]
The New York Times claimed that aliens must have existed at some point. But science is less certain. “There are two possible outcomes: if the result confirms the hypothesis, then you’ve […]
Spirals and ellipticals rule the Universe, but every so often, something far more intricate shows up. “For me, the study of these laws is inseparable from a love of Nature […]
If we look to the distant future, with unlimited technology, how far could we reach? “Even if I stumble on to the absolute truth of any aspect of the universe, I […]
Happy Birthday To The Person Who Literally Brought Us The Entire Universe “Equipped with his five senses, man explores the universe around him and calls the adventure Science.” –Edwin Hubble As […]
It’s the most mysterious “stuff” our Universe has. So why are we so sure it’s real? “The Universe is made mostly of dark matter and dark energy, and we don’t know […]
Just two days before its data was released, I wrote this story on what it all means. Come get the scoop! “Einstein’s gravitational theory, which is said to be the greatest […]
An update on the star 1,480 light-years away that gave us hope we weren’t alone in the universe.
Sometimes, space itself comes with its own magnifying lens. “We see the world through the lens of all our experiences; that is a fundamental part of the human condition.” –Madeleine […]
And why it might spell trouble for dark energy as we know it. “That’s all regular matter, just five percent. A quarter is “dark matter,” which is invisible and detectable only […]
The ability for mass to bend and magnify background light is a unique feature of General Relativity. But it can fool us, too. “Gravitational and electromagnetic interactions are long-range interactions, meaning […]
An incredible live-blog of an incredible event. “It’s becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new […]
There are likely no more than five this big, this early in the entire Universe. “Based on our understanding of how galaxy clusters grow from the very beginning of our […]
When they ask, will you tell them the truth, or something comforting? Why not do both! “It is possible to commit no mistakes and still lose. That is not a weakness, […]
13.8 billion years is a great number. But how sure are we of this, and how did we get there? “Nobody grows old merely by living a number of years. We […]
Not water, not ice, and definitely not aliens. Here’s how we know. “You are the salt of the earth. But remember that salt is useful when in association, but useless in […]
Those white spots are still salt, but there’s so much more there! “Although impact processes dominate the surface geology on Ceres, we have identified specific color variations on the surface […]
Is it how the Universe began, or just how our observable Universe began? They’re not the same! “These theories were based on the hypothesis that all the matter in the universe […]
Don’t even think about getting anything other than this one! “No one regards what is before his feet; we all gaze at the stars.” –Quintus Ennius If you are (or you […]
If they shoot out straight lines of high-energy particles, why do they carve bubble-like shapes? “When a person starts to talk about their dreams, it’s as if something bubbles up […]
Planet Nine? More like “Planet maybe.” “Finding out that something you have just discovered is considered all but impossible is one of the joys of science.” –Mike Brown Last week, the […]
These stars are too hot and blue for their age, and the leading theory just got a strike against it. “Youth is the gift of nature, but age is a work […]
What LIGO’s first signal actually means. “Ladies and gentlemen, we have detected gravitational waves.” –David Reitze This morning, the principal investigator of the Laser Interferometer Gravitational-wave Observatory (LIGO), David Reitze, made […]
