Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute in New York City. Paul received his PhD in Physics from the University of Illinois at Urbana-Champaign in 2011, and spent three years at the Paris Institute of Astrophysics, followed by a research fellowship in Trieste, Italy, His research focuses on many diverse topics, from the emptiest regions of the universe to the earliest moments of the Big Bang to the hunt for the first stars. As an "Agent to the Stars," Paul has passionately engaged the public in science outreach for several years. He is the host of the popular "Ask a Spaceman!" podcast, author of "Your Place in the Universe" and "How to Die in Space" and he frequently appears on TV — including on The Weather Channel, for which he serves as Official Space Specialist.
Any day now, it could happen: We could detect an asteroid on an Earth-crossing trajectory. It might be tomorrow; it might be a thousand years from now. So what can we do about it?
Directly mapping the Milky Way is an extremely challenging task, but observations of other galaxies helped us piece together what our home galaxy looked like.
One astronomer proposes that, instead of building gigantic, expensive experiments on Earth, we should try another method of searching for dark matter: Looking to the stars.
Scientists modeled how black holes and neutron stars form after dying stars collapse, and explained why some get a hard 'kick' into interstellar space.
Some physicists have hypothesized that in the earliest moments of the Big Bang, the forces of nature were so extreme and so exotic that they could have supported the growth of complex structures.
In an age of diminishing trust in science, scientists need to change how they work with the public and within the broader scientific community.
An astronomer has outlined a way for methane-producing life to thrive in the molecular clouds of deep space, opening up a new pathway to understanding the potential origins and diversity of life.
Due to the mind-blowing distances and speeds required, interstellar travel remains a major spaceflight challenge. But new research highlights yet another hurdle: Communication blackouts.
Space mysteries Even though the density of interstellar space is billions of times lower than even our emptiest human-made vacuum chambers, it's not 100% percent empty.
Humanity's ability to track and monitor celestial cycles stretches back into prehistory, long before the invention of telescopes and astrolabes.
Astronomers developed a sophisticated computer simulation to explore whether or not strange star Betelgeuse may be the result of a merger between two smaller stars.
Space is a dangerous place, especially when it comes to high-energy particles, and intense solar activity can pose threats to people and technology on Earth.
The hellish super-Earth '55 Cancri e' may be constantly losing and re-growing its atmosphere, a new study of the planet's strange transit signals suggests.
We all know the universe contains a vast array of elements, ranging from light gases, such as helium, to heavy metals, like lead. But where did all of the elements come from?
When complete, the Square Kilometer Array Observatory (SKAO) will be the world's most powerful radio telescope — if SpaceX's Starlink satellites don't ruin its view.
Researchers have shared a radical new idea for how to put a spacecraft in orbit around Neptune: Use the thin atmosphere of Triton, Neptune's largest moon, to capture it.
Scientists worldwide are already using artificial intelligence and machine learning to sort through huge amounts of data, suggesting that the future of astronomy belongs to AI.
In the extreme hearts of neutron stars, fundamental particles are twisted into strange 'pasta' shapes that could reveal untold secrets about how dead stars evolve.
Humanity is slowly losing access to the night sky, and astronomers have invented a new term to describe the pain associated with this loss: 'noctalgia,' meaning 'night grief.'
The outer solar system contains a striking crime scene with a big mystery: How did Neptune get a moon like Triton?
As the search for "Planet Nine" in the outer solar system continues, new research suggests there may be an Earth twin buried deep within the frozen waste of the Kuiper Belt beyond Neptune.
