The Japanese X-ray satellite SUZAKU has looked at the distribution of gas around the Virgo cluster, a large galaxy cluster close to the Milky Way and the second brightest in X-rays. It discovered that the elements needed to make living organisms, planets and spiced-up stars are equally distribute...

Does the specific location of a solar system within a galaxy affect the solar system’s structure? Like does distance from the centre affect how big the star is, or what kind of planets form? Stuart, London Indirectly yes. You have more gas on the outskirts than in the central regions.

Short Answer - the temperature of a black hole is inversely proportional to its mass. For a black hole with the same mass as our Sun the temperature is 60 billionths of a degree kelvin.
How About That?
Iapetus is the third largest satellite of Saturn, and it is the largest object in the solar system not in hydrostatic equilibrium. Iapetus is a moon of Saturn known for its colour dichotomy. It has a dark side and white side, and it is often called the Yin Yang moon.

Are Mimas and Miranda the smallest known objects in hydrostatic equilibrium? Dan – London This question relates to the shape of astrophysical objects and as we discussed in the past, it’s an important characteristic of stars, and it’s in the definition of “planet”.

A new paper accepted for publication this month has highlighted how spiral galaxies came to form in the early Universe. By using the power of the Atacama Large Millimeter/submillimeter Array (ALMA), a team lead by Roberto Maiolino has individuated the mechanism through which galaxies gather stell...

In this vlog, I talk about Prof. Payne-Gaposchkin, one the most important astronomers of the 20th Century. Thanks to her we know that stars are not made by the same elements as the Earth, and that Hydrogen is the most abundant element in the Universe.
Exoplanet
In the almost 20 years since the discovery of the first exoplanet orbiting a main-sequence star, we have gone from thinking that planets are a cosmic curiosity to a common feature of the Universe. The race is on to find a true Earth twin, to measure an exoplanet atmosphere or, when the James Webb...

We all get the munchies, but when you’re a supermassive black hole (SMBH) your hunger might have dire consequences. And just like that an SMBH has outgrown its galaxy and jumped to the top of the heavyweight objects in the universe.

As I mentioned in a previous post, there are a few ways to measure the distance of a star in our galaxy. Unfortunately when the Luminosity is unknown and it is too far away to use parallaxes method, we are stumped for ways to estimate the distance.

Pluto, not to be confused with Micky Mouse’s dog, is going to be in the news a lot soon, as we are finally going to take a closer look to the elusive dwarf planet. Pluto Stats: Discovered by Clyde Tombaugh on the 18th of February 1930, it is smaller than our Moon with a 1184 […]
