The April 8 solar eclipse is a gift that keeps on giving. You may also be able to see planets, and even a "devil comet" — in ...

A brilliant comet waved its tail above the site of the world's largest telescope as it lit up the night sky last month.

Recent observations collected on the Comet Observation database (COBS) suggest that, on Jan. 2, 2025, G3 ATLAS experienced a sudden outburst, showing a nearly four-fold increase in apparent ...

By then, however, the comet's close proximity to the sun was making ground observations increasingly difficult as the comet's altitude was placing it progressively closer with each passing morning ...

"The thermal stress may have been too much." The latest development is surprising, considering that initial observations of the comet after perihelion suggested it had remained unaffected by its ...

the time at which the comet is close to the sun. Each observation of a comet position gives two co-ordinates, right ascension and declination; and hence to determine the five -elements ...

SHANGHAI -- Chinese scientists have attributed the sudden movement of a boulder on the surface of a comet to a phenomenon ...

STEREO’s observations highlight the streaky appearance of the comet’s tail. A processed image from STEREO makes the tail really pop. “I think the remarkable thing is the heavily striated ...

The comet at the time was a magnitude 19 object about 4.38 AU (655 million km) from Earth. Further observations indicated it had a diffuse coma about 4.5 arcseconds across and a straight tail.

PROF. SIMON SCHAFFER:'Halley collated tables of all the comet observations he could find, 'looking for similarities in their behaviour. 'What direction they came from. 'How close they got to the sun.

The findings, published in The Astrophysical Journal, are based on data captured by the European Space Agency's (ESA) Rosetta mission during its two-year close flyby and observation of the comet ...
