GRB 980703: A Reassuring Redshift - July 13th, 1998.

"In the old days, during 1997, astronomers had little idea of the true distance to gamma-ray bursts. Did these enigmatic explosions occur in our outer galaxy, or in the outer Universe? In May, 1997, a first telling distance measure was made - GRB 970508 showed an absorption line with a redshift of about 0.8 - indicating that this gamma-ray burst (GRB) was an enormous distance away. Skeptics, however, are not always convinced by an unrepeated measurement. Since then, though, other tantalising coincidences had occurred: GRB 971214 occurred unusually near a galaxy with the enormous redshift of 3.4, and GRB 980425 occurred unusually near a low-redshift supernova. Skeptics were intrigued. The potentially definitive implications of the above-pictured optical transient might impress even the cautious. GRB 980703's optical transient shows a well-measured redshift from both an absorption line and an emission line: 0.97. The above negative highlights the uncommon transient source with the label "OT", while letters designate common comparison stars."

Beautiful Eye Cosmic!

Cosmic eye staring right back at us, from 16 million light-years away!

This spectacular image captures the spiral galaxy Messier 94, symbolically nicknamed the Crocodile's Eye galaxy, located in the constellation Canes Venatici. This isn't just a sinple photograph, but a composite masterpiece created by #NASA. It blends X-ray data gathered by the #Chandra X-ray Observatory with optical and infrared images.

Surrounding its brilliant core, you can see a massive inner ring. This is a starbust region, where new stars are being born at a dizzying and violent pace. Hot gas and extreme energy explode in electric shades of purple and pink.
