While astronomers have observed white dwarfs consuming companion stars on numerous occasions, for the first time, they have now observed the consumption of the companion’s helium and not just hydrogen.
In 2010, gamma ray observations by Fermi Space Telescope revealed an unknown mysterious structure of our home galaxy Milky Way later known as Fermi Bubbles.
Last week we make you sad about the future of the humanity, the Earth, the Sun and the Solar System. Today we’ll look far, far forward into the distant future of the Universe, at timescales that we can barely comprehend.
Don’t presume to assume. Did the Universe really start from a single point? How unusual is the Earth? Let’s explore the answer with @CheapAstro at #365DaysOfAstro
What if our Universe was just one in an infinite number of parallel universes; a possible outcome from the specific predictions of quantum mechanics. The idea of multiple universes is common in science fiction, but is there any actual science to back this theory up?
As astronomers look out across the Universe. They see various objects spewing jets of material light years into space. What causes these jets? And what impact do they have on the Universe?
What makes the Big Bang theory so successful? How were alternatives ruled out? What are the electric universe and steady state theories? Do any other options remain, like conformal cyclic cosmology?
The Hubble Constant tells us how fast the universe is expanding. However, different methods of measuring the Hubble Constant give different results. In this podcast, NOIRLab’s John Blakeslee describes data his team has collected to help resolve this discrepancy.
What is a vacuum, and what makes a false one? What happened in the early universe to bring about our current physics? Will it happen again? If so, when?
Today Cosmic Savannah talk with Sambatriniaina Rajohnson about her work on large scale structure of the universe and her plan to observe these structure in Vela supercluster region using MeerKAT.
