Even on the golf course, Gemini celebrates National Dance Day :)
A rumbling quickly startled her, and she looked up at the scraps of metal moments before an explosion shot from the broken machinery. A fireball rose and filled the air in a matter of seconds. It raced towards her as bits of metal, glass, and wire were hurled along with it.
Her heartbeat fluttered so quickly that she lost her breath, and her eyes were squeezed shut.
She felt heat, but it did not get any warmer.
She opened her eyes. The fireball hung in the air as if it had frozen. The metal, glass, and wire were equally unmoving. She was still breathing hard…
The metal tag jingled as she staggered into brambles and fallen branches from the thickening forest. Her shoulder struck a tree and she spun backwards until her back struck another. Her forehead ached and she felt lightheaded.
I need to move.
But I can’t…
She collapsed to her knees and tried to catch her breath. Deep red ran into her left eye, and she had to shut it again. Her hands wrapped around her stomach. The metal tag jingled around her neck. She shut her eyes against its words.
A galaxy with a glowing heart
This view, captured by the NASA/ESA Hubble Space Telescope, shows a nearby spiral galaxy known as NGC 1433. At about 32 million light-years from Earth, it is a type of very active galaxy known as a Seyfert galaxy — a classification that accounts for 10% of all galaxies. They have very bright, luminous centres comparable to that of our galaxy, the Milky Way.
Galaxy cores are of great interest to astronomers. The centres of most, if not all, galaxies are thought to contain a supermassive black hole, surrounded by a disc of infalling material.
NGC 1433 is being studied as part of a survey of 50 nearby galaxies known as the Legacy ExtraGalactic UV Survey (LEGUS). Ultraviolet radiation is observed from galaxies, mainly tracing the most recently formed stars. In Seyfert galaxies, ultraviolet light is also thought to emanate from the accretion discs around their central black holes. Studying these galaxies in the ultraviolet part of the spectrum is incredibly useful to study how the gas is behaving near the black hole. This image was obtained using a mix of ultraviolet, visible, and infrared light.
LEGUS will study a full range of properties from a sample of galaxies, including their internal structure. This Hubble survey will provide a unique foundation for future observations with the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA). ALMA has already caught unexpected results relating to the centre of NGC 1433, finding a surprising spiral structure in the molecular gas close to the centre of NGC 1433. The astronomers also found a jet of material flowing away from the black hole, extending for only 150 light-years — the smallest such molecular outflow ever observed in a galaxy beyond our own.
