How You Can See A Close-Up Of The Dazzling Planet Tonight Through A ‘Virtual’ Telescope

Can you see Mars at night? Yes—right now you can see Mars from Earth by looking due east as soon as the Sun sets in the west. Mars is today at opposition so as bright as it ever gets. 

However, if you want to get an extra-special close-up then Lowell Observatory in Flagstaff, Arizona is streaming a special “Virtual Mars Series” of planet-gazing events on YouTube.

During these live webcasts you’ll be able to see real-time close-ups of the red planet through a huge 14-inch “virtual telescope.”

Sharpness of star-forming image matches expected resolution of Webb Space Telescope — ScienceDaily

NASA’s James Webb Space Telescope is still more than a year from launching, but the Gemini South telescope in Chile has provided astronomers a glimpse of what the orbiting observatory should deliver.

Using a wide-field adaptive optics camera that corrects for distortion from Earth’s atmosphere, Rice University’s Patrick Hartigan and Andrea Isella and Dublin City University’s Turlough Downes used the 8.1-meter telescope to capture near-infrared images of the Carina Nebula with the same resolution that’s expected of the Webb Telescope.

Hartigan, Isella and Downes describe their work in a study published online this week in Astrophysical Journal Letters. Their images, gathered over 10 hours in January 2018 at the international Gemini Observatory, a program of the National Science Foundation’s NOIRLab, show part of a molecular cloud about 7,500 light years from Earth. All stars, including Earth’s sun, are thought to form within molecular clouds.

“The results are stunning,” Hartigan

Hubble Space Telescope watches stunning supernova fade over a full year

Tens of millions of years ago, the corpse of a star stole away too much gas from a neighbor and exploded, becoming a beacon in the cosmos — one that took a full year to fade away.

Fortunately for scientists, the massive stellar explosion, called supernova 2018gv, took place 70 million light-years away, and the Hubble Space Telescope was in prime position to watch the lightshow. Astronomers used the instrument to create a timelapse showing the supernova’s year-long fade, from February 2018, shortly after the explosion was first detected, through February 2019.

“No Earthly fireworks display can compete with this supernova, captured in its fading glory by the Hubble Space Telescope,” Adam Riess, an astrophysicist at the Space Telescope Science Institute and Johns Hopkins University in Maryland and leader of the team behind the new footage, said in a statement.

Very Large Telescope finds 6 galaxies trapped in web of supermassive black hole

Oct. 1 (UPI) — Using the Very Large Telescope, a powerful observatory in Chile, astronomers have identified six galaxies trapped in the web of a supermassive black hole when the universe was just 900 million years old.

The discovery, described Thursday in the journal Astronomy and Astrophysics, helps explain how supermassive black holes got so big so soon after the Big Bang.

“This research was mainly driven by the desire to understand some of the most challenging astronomical objects — supermassive black holes in the early universe,” lead study author Marco Mignoli said in a news release.

“These are extreme systems and to date we have had no good explanation for their existence,” said Mignoli, an astronomer at the National Institute for Astrophysics in Italy.

The findings lend support to the theory that web-like structures of gas fueled the rapid growth of supermassive black holes in the early universe. When

ESO telescope spots galaxies trapped in the web of a supermassive black hole
With the help of ESO’s Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole, the first time such a close grouping has been seen within the first billion years of the Universe. This artist’s impression shows the central black hole and the galaxies trapped in its gas web. The black hole, which together with the disc around it is known as quasar SDSS J103027.09+052455.0, shines brightly as it engulfs matter around it. Credit: ESO/L. Calçada

With the help of ESO’s Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole when the Universe was less than a billion years old. This is the first time such a close grouping has been seen so soon after the Big Bang and the finding helps us better understand how supermassive black holes, one of which exists at the centre of our Milky

Stunning images from Hubble, Chandra, and more reveal value of space telescope teamwork

What do you get when you put a space telescope to work with another space telescope or two? Amazing compilation images of our universe.

NASA recently highlighted some collaborations between its Chandra X-ray Observatory and other telescopes, particularly the Hubble Space Telescope, showing what sorts of images can be produced when you look at the same object in different wavelengths of light.

The galaxy M82 can be seen edge-on from Earth, allowing scientists a great perspective whenever star formation occurs, since there is little to block our view. Chandra observations, visible in blue and pink, show bursts of high temperatures created when gas is heated by supernova explosions. The Hubble Space Telescope’s optical images (shown in red and orange) reveal the galaxy’s shape.

James Webb Telescope Will Look for Life Around Dead Stars

When NASA’s James Webb Space Telescope launches next year, it may be able to find indications of life beyond our planet in an unexpected location — on planets which orbit dead stars called white dwarfs.

A recent study found an intact planet orbiting around a white dwarf, which surprised astronomers as in their death throes these stars usually destroy the planets around them when they swell before collapsing to form the white dwarf. But this planet somehow survived, giving a clue to a new type of location where we could search for habitable planets.

“If rocky planets exist around white dwarfs, we could spot signs of life on them in the next few years,” Lisa Kaltenegger, one of the authors of the new study and associate professor of astronomy in the College of Arts
