Everything you wanted to know about the first ever image of a black hole

Space
The Event Horizon Telescope has released the first direct image of a black hole and its neighbourhood. This black hole lurks in the centre...

VLA Makes First Direct Image of Key Feature of Powerful Radio Galaxies

Space
Astronomers used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to make the first direct image of a dusty, doughnut-shaped feature...
This artist’s impression shows a computer generated model of the Milky Way and the accurate positions of the globular clusters used in this study surrounding it. Scientists used the measured velocities of these 44 globular clusters to determine the total mass of the Milky Way, our cosmic home. Credit: ESA/Hubble, NASA, L. Calçada

Hubble & Gaia accurately weigh the Milky Way

Space
The mass of the Milky Way is one of the most fundamental measurements astronomers can make about our galactic home. However, despite decades of...

Physicists analyze rotational dynamics of galaxies and influence of the photon mass

Space
The rotating stars in our galaxy are puzzling as same as our milky way. Various scientists have suggested that the orbital speeds of stars...
This image shows the merger of two galaxies, known as NGC 7752 (larger) and NGC 7753 (smaller), also collectively called Arp86. In these images, different colors correspond to different wavelengths of infrared light. Blue and green are wavelengths both strongly emitted by stars. Red is a wavelength mostly emitted by dust.

Why do some galactic unions lead to doom?

Space
NASA's Spitzer Space Telescope recently releases some pictures that show pairs of galaxies on the cusp of cosmic consolidations. Even though the galaxies appearing...
This image, taken with Hubble’s Advanced Camera for Surveys shows a part the globular cluster NGC 6752. Behind the bright stars of the cluster a denser collection of faint stars is visible — a previously unknown dwarf spheroidal galaxy. This galaxy, nicknamed Bedin 1, is about 30 million light-years from Earth. Credit: ESA/Hubble, NASA, Bedin et al.

Hubble fortuitously discovers a new galaxy in the cosmic neighbourhood

Space
Astronomers using the NASA/ESA Hubble Space Telescope to study some of the oldest and faintest stars in the globular cluster NGC 6752 have made...
This gigantic image of the Triangulum Galaxy — also known as Messier 33 — is a composite of about 54 different pointings with Hubble’s Advanced Camera for Surveys. With a staggering size of 34 372 times 19 345 pixels, it is the second-largest image ever released by Hubble. It is only dwarfed by the image of the Andromeda Galaxy, released in 2015. The mosaic of the Triangulum Galaxy showcases the central region of the galaxy and its inner spiral arms. Millions of stars, hundreds of star clusters and bright nebulae are visible. This image is too large to be easily displayed at full resolution and is best appreciated using the zoom tool. Credit: NASA, ESA, and M. Durbin, J. Dalcanton, and B. F. Williams (University of Washington)

Hubble takes gigantic image of the Triangulum Galaxy

Space
The NASA/ESA Hubble Space Telescope has captured the most detailed image yet of a close neighbour of the Milky Way — the Triangulum Galaxy,...
An artist’s concept of a super-Earth in the habitable zone of a star smaller and cooler than the sun. Such large planets could have long-lasting magma oceans that generate magnetic fields capable of protecting incipient life. The graphic was created to model Kepler-62f, one of many exoplanets discovered by NASA’s now inoperable Kepler space telescope. (Image courtesy of NASA Ames/JPL-Caltech/Tim Pyle)

What magnetic fields can tell us about life on other planets?

Science
Earth has a magnetic field – it’s what makes compasses align north-south and lets us navigate the oceans. It also protects the atmosphere, and...

Finding the happy medium of black holes

Space
Using data from NASA's Chandra X-ray Observatory and other telescopes, scientists have taken major steps in their hunt to find black holes. Through this...
