The comet is gradually brightening, but it has recently faded slightly from its peak brightness. The latest reported magnitude is around 7.5 to 8 and improving (lower number means brighter). The magnitude might reach 4.5 to 5 at its brightest, but it will likely be close to the horizon.

The comet appears as a small green sphere due to the presence of diatomic carbon (C2) in its coma. Long-exposure images show a faint tail extending for more than two moon diameters.

If the comet survives its closest approach to the sun (perihelion) around May 1, 2025, it might become visible in the evening sky (dusk) during the first days of May. It will pass about 31 million miles from the sun, inside Mercury's orbit.

Synthetic flagella spin and contract at the expense of chemical fuel

We show that microns-long ribbons assembled from small peptides catalyze the conversion of chemical fuel. This conversion drives the ribbons’ morphological change from flat to helical and tubular form...

The impact of climate change on Antarctic volcanism is still largely unknown, but it's a crucial area of research.

Coffee Table Science @coffeetablescience.bsky.social · Jan 9

During past deglaciation periods, reduced pressure from melting ice led to increased volcanic activity. This could happen again, potentially triggering a dangerous feedback loop: more eruptions, more ice melt, and further warming.

Antarctica, a land of ice, also harbors a fiery secret: dozens of volcanoes. While most are dormant, the melting of ice sheets due to climate change could potentially reactivate them.
