Hubble captures the site of an epic supernova, spotted by amateur astronomers

The eyes of the astronomy community are firmly on one event this week: The launch of the James Webb Space Telescope, the brand-new space observatory from NASA, the European Space Agency, and the Canadian Space Agency, which will be the world’s most powerful space telescope and the successor to the Hubble Space Telescope. But that launch doesn’t mean that Hubble will be going away, as the older telescope will continue to be used to capture beautiful images of space in the visible light spectrum, while James Webb will focus primarily on capturing data in the infrared wavelength.

This week’s image from the Hubble Space Telescope is an example of the striking visuals it is still possible to capture with this 30-year-old technology. It shows the galaxy NGC 3568, a barred spiral galaxy (like our Milky Way) which is located around 57 million light-years away in the constellation of Centaurus.

One distinct feature of this galaxy is that it was the location of a huge supernova, when a star reached the end of its life and exploded in a dramatic cosmic event. The light from this supernova reached Earth in 2014 and, unusually, was spotted not by professional astronomers but by a team of amateur astronomy enthusiasts who watch for supernovas from their backyards.

“While most astronomical discoveries are the work of teams of professional astronomers, this supernova was discovered by amateur astronomers who are part of the Backyard Observatory Supernova Search in New Zealand,” the European Space Agency writes. “Dedicated amateur astronomers often make intriguing discoveries — particularly of fleeting astronomical phenomena such as supernovae and comets.”

Water was present in our solar system before the sun formed
This artist’s impression shows the planet-forming disc around the star V883 Orionis. In the outermost part of the disc water is frozen out as ice and therefore can’t be easily detected. An outburst of energy from the star heats the inner disc to a temperature where water is gaseous, enabling astronomers to detect it. The inset image shows the two kinds of water molecules studied in this disc: normal water, with one oxygen atom and two hydrogen atoms, and a heavier version where one hydrogen atom is replaced with deuterium, a heavy isotope of hydrogen.

You might assume that there has always been water on Earth -- that water was there from the very beginning when our planet formed. But scientists increasingly think that water on Earth may have originated elsewhere, and been carried here by comets. However, the water in the comets had to come from somewhere, and astronomers recently made a discovery which could shed light on how that water was found in the solar system.

The researchers used the Atacama Large Millimeter/submillimeter Array (ALMA), a radio telescope array in Chile, to study a planet-forming disc around the star V883 Orionis, looking for water there to see how it would be transported as the disk evolves into planets.

Hubble captures a messy irregular galaxy which hosted a supernova
The irregular spiral galaxy NGC 5486 hangs against a background of dim, distant galaxies in this image from the NASA/ESA Hubble Space Telescope. The tenuous disk of the galaxy is threaded through with pink wisps of star formation, which stand out from the diffuse glow of the galaxy’s bright core.

This week's image from the Hubble Space Telescope shows a dramatic spiral galaxy called NGC 5486, which is shot through with wisps of pink showing regions where new stars are being born.

Located 110 million light-years away in the famous constellation of Ursa Major, this galaxy is a type called an irregular spiral galaxy because its arms are wandering and indistinct. If you compare the image of this galaxy to one of a quintessential spiral galaxy like NGC 2336, you'll see that a non-irregular spiral galaxy has clearly defined arms that reach out from its center and are symmetrical.

How James Webb is peering into galaxies to see stars being born
Researchers are getting their first glimpses inside distant spiral galaxies to see how stars formed and how they change over time, thanks to the James Webb Space Telescope’s ability to pierce the veil of dust and gas clouds.

Recently astronomers used the James Webb Space Telescope to look at the structures of dust and gas which create stars in nearby galaxies. Now, some of the researchers have shared more about the findings and what they mean for our understanding of how galaxies form and evolve.

The project, called Physics at High Angular resolution in Nearby Galaxies, or PHANGS, used James Webb to observe several galaxies which are similar to our own Milky Way to see how stars are forming within them.
