Dwarf

Valparaiso University Professor of Physics and Astronomy Todd Hillwig, Ph.D., is the sole American researcher involved in an international project using the Hubble Space Telescope to learn more about the universe. Hillwig received a…

Astronomers have long known how planets form, but the when of it has always been unclear. If a Cambridge University team's conclusion from a study of white dwarf stars proves correct, that question has been answered. The debate is…

The James Webb Space Telescope has snapped a remarkably detailed image of a nearby dwarf galaxy. The…

Ask astronomers about dark matter and one of the things they talk about is that this invisible, mysterious “stuff” permeates the universe. In particular, it exists in halos surrounding most galaxies. The mass of the halo exerts a strong…

Scientists have identified a star that, they say, survived a massive explosion and ended up being brighter than before. The star is a kind known as a “white dwarf.” These are very dense objects that have a mass about equal to the sun.…

Weeks after astronomers released a historic image of the Milky Way's supermassive black hole, Sagittarius A*, a separate study showed how it is probing the evolution of black holes in dwarf galaxies.A new analysis of dwarf galaxy…

We all know that a humongous black hole exists at the center of our galaxy. It’s called Sagittarius A* (Sgr A* for short) and it has the mass of 4 million suns. We’ve got to see a radio image of it a few weeks back, showing its…
