This image shows an irregular galaxy named IC 10, a member of the Local Group — a collection of over 50 galaxies in our cosmic neighborhood that includes the Milky Way.

Hubble captures elusive, irregular galaxy

Recently Hubble captured an image of an irregular galaxy named IC 10, a losest-known starburst galaxy. The galaxy is experiencing a furious bout of...

Cold quasars could rewrite our understanding of a galaxy’s lifecycle

A Cold quasar is a galaxy with a quasar at the center and abundant cold gas that can still produce new stars. Gas falling...
This Hubble image shows the barred spiral galaxy NGC 7773. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

An amazing new image of the barred spiral galaxy NGC 7773

The striking image you can see above was taken by the ESA (European Space Agency) that features a barrel spiral galaxy known as NGC...
This image shows how the inner region of the accretion disk (red) aligns with the equatorial plane of the black hole. The outer disk is tilted away. The inner disk (where the black curve dips) is horizontal, signaling the long-sought Bardeen-Petterson alignment.

40 year black hole mystery solved with most detailed simulation ever

Using a custom built code and a supercomputer, an international team of scientists has created the most detailed, highest resolution simulation of a black...
This artist's illustration shows what one of the very first galaxies in the Universe might have looked like. High levels of violent star formation and star death would have illuminated the gas filling the space between stars, making the galaxy largely opaque and without a clear structure.

Universe’s earliest galaxies were brighter than expected

Using NASA's Spitzer Telescope, astronomers have recently found cues on how galaxies lit up the universe. According to their findings, some of the Universe's...

Jets and winds from galaxy cores appear to share a common cause

Fundamental considerations of the energy supply in large-scale extragalactic radio sources("radio galaxies") led astronomers to predict that these sources should contain jets or beams...
Astronomers developed a mosaic of the distant Universe, called the Hubble Legacy Field, that documents 16 years of observations from the NASA/ESA Hubble Space Telescope. The image contains 200,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the Big Bang. The new set of Hubble images, created from nearly 7,500 individual exposures, is the first in a series of Hubble Legacy Field images. The image comprises the collective work of 31 Hubble programs by different teams of astronomers. Hubble has spent more time on this small area than on any other region of the sky, totaling more than 250 days, representing nearly three-quarters of a year. The team is working on a second set of images, totaling more than 5,200 Hubble exposures, in another area of the sky.

2,65,000 galaxies in an extensive legacy field mosaic

NASA's Hubble Space Telescope has recently captured an image of a legacy field, showing 2,65,000 galaxies, each at different stages in their life cycles,...
This is a ground-based telescope’s view of the Large Magellanic Cloud, a satellite galaxy of our Milky Way. The inset image, taken by the Hubble Space Telescope, reveals one of many star clusters scattered throughout the dwarf galaxy. Credit: NASA, ESA, Adam Riess, and Palomar Digitized Sky Survey

Hubble measurements confirmed: Universe is outpacing all expectations of its expansion rate

The universe is expanding about 9% faster than expected based on its trajectory seen shortly after the big bang. This new revelation is made...

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

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