Have astronomers disproved the Big Bang?

If there’s a question that you guys never expected me to ever ask, it might be “have astronomers disproved the Big Bang?” And I understand why you might think that. After all, in my videos, I describe what scientists know about the most cutting-edge topics in physics research. So, perhaps I should be up front… Read More »

Astronomers Find Vortex Around A Black Hole Spinning At 70% the Speed of Light

Black holes are going to kill you and everyone you love. Well, maybe. As one of the most powerful forces in the universe, black holes were originally believed to be a myth for centuries, and were only recently proven to in fact exist by modern science. Way back in 1687, Newton blew the mind of… Read More »

Astronomy & Telescopes : How to Use a Telescope With Setting Circles

So today we’re going to talk about setting circles on telescopes. So first off, to back up a little bit, every object in the sky has a coordinate associated with it. That coordinate is the right ascension and the declination, which is basically like a latitude and longitude on the sky. So, the steady circles… Read More »

Astronomy & Telescopes : How to Focus a Telescope

So let’s talk a little bit about focusing telescopes. Whenever you focus a telescope, basically the only thing you’re doing is changing the facing between the optical elements, whether that be a mirror or a lens or anything in between. As so there are a variety of ways that telescopes can be focused. So the… Read More »

When art meets astronomy (UCL)

Most of my work involves nature, geology, technology and ideas of space and time and distance and collapsing distance. Most of my works have involved collaborating with people in different fields and disciplines. We’re all astronomers, so we look at things through a particular way, a particular methodology. Having Katie in the corridor has brought… Read More »

Supernovae – 60 Second Adventures in Astronomy (2/14)

60-Second Adventures in Astronomy. Number 2: Supernovae. One of the most mind-blowing events in the universe is the explosion of a star. In 1054 CE Chinese astronomers spotted one so bright they could see it in daylight. Today you can still see a cloud of gas and dust from the same explosion and because a… Read More »

Astronomers Discover Mystery Radio Signal From Another Galaxy

The date is 2001, and in the Australian outback a 64 meter radio telescope scans the sky for electromagnetic signals from deep space. With most of the electromagnetic energy in the universe being generated by stars and black holes, and outside of the visible light spectrum, the radio dish and the data it collects as… Read More »

How Gaia Changed Astronomy Forever | Space Time

The great advances in any science tend to come in sudden leaps April 25th of 2018 marks the beginning of just such a leap for much of astronomy. In the early hours of the morning the Gaia mission second data release dropped. Our understanding of our own galaxy will never be the same again. The… Read More »
