10 billion light-years away...

Giant Star Seen 150 Days Before it Exploded as a Supernova !

In April of 2023, a massive star exploded in NGC 4388, a spiral galaxy about 57 million light-years away. The Zwicky Transient Facility (ZTF) spotted it, and the supernova is called SN 2023 fyg. SN 2023fyq is a rare type of supernova called a Type Ibn.

They show a lack of hydrogen lines and narrow He I emission lines in their spectra. Astronomers think that these characteristics come from the SN interacting with hydrogen-poor, helium-rich circumstellar material (CSM.)

Comet ZTF c/2022 e3

So named after it's discovery by the Zwicky Transient Facility on 2 March 2022, this comet will be at it's closest approach to Earth on February 1st at a distance of .28 AU (or 42 Million KM).

The Comet is expected to get brighter than Mag 6, making it just about visible to the naked eye, making it impossible to see unless you're in a dark country setting.

Comet-like plumes are blowing over the volcanic peaks of Mount Etna in this wintry mountain-and-skyscape from planet Earth. The stacked and blended combination of individual exposures recorded during the cold night of January 23 also captured naked-eye Comet ZTF just above Etna's snowy slopes. Of course, increasing sunlight and the solar wind are responsible for the comet's greenish coma and broad dusty tail. This weekend, Comet ZTF is dashing across northern skies between north star Polaris and the Big Dipper. From a dark site, you can only just spot it as a fuzzy patch, though. That's still an impressive achievement if you consider you are gazing at a visitor from the distant Oort cloud with your own eyes. But binoculars or a small telescope will make for an even more enjoyable view of this Comet ZTF in the coming days.

42 degrees in the sky and outside! Hello ZTF!!!

Look to my coming on the first light of the fifth day, at dawn look to the east :
