The photocopied “sunburst” from the early Universe
Find out how astronomers have used the brightest known (to date) gravitationally lensed galaxy to learn about the early Universe.
A New H0pe for the Hubble Constant?
The Hubble Tension is one of the great mysteries of modern cosmology…can today’s paper help us solve it?
How to tell if a Black Hole is making your fairy lights twinkle
Are your fairy lights being warped by a black hole this holiday season? Find out in today’s post!
Forget X-Ray Vision: Using Gravitational Waves to Peer Inside of the Sun
What if we could use continuous gravitational waves from far away pulsars to learn about the inside of our very own sun? The authors of today’s paper explore what it would take to make this far-out idea a reality.
Holy Cow! Is our journey through the universe the reason for the Hubble Tension?
We move through the universe relative to the Cosmic Microwave Background. Could our movement cause our measurements of the Hubble constant to be biased?
Gravitational Lensing Unveils an Ultramassive Black Hole In the Heart of Abell 1201
Measuring the mass of black holes in the centers of far away galaxies can be tricky, but today’s paper demonstrates the viability of a new method in this field: gravitational lensing!
