Jake Rosenthal takes us on a tour of the history of discovery of our place in the cosmos.

DPS/EPSC update: 2007 OR10 has a moon!

Emily Lakdawalla • October 19, 2016

The third-largest object known beyond Neptune, 2007 OR10, has a moon. The discovery was reported in a poster by Gábor Marton, Csaba Kiss, and Thomas Mueller at the joint meeting of the European Planetary Science Congress and the Division for Planetary Sciences of the American Astronomical Society (DPS/EPSC) on Monday.

Rapidly Rotating Regular Satellites and Tides

Darin Ragozzine • October 17, 2016

Pluto’s small moons have unusual rotation rates and states. Now we know a moon of another dwarf planet does as well. Is there a connection?

A moon with atmosphere

Emily Lakdawalla • April 08, 2015

What is the solar system moon with the densest atmosphere? Most space fans know that the answer is Titan. A few of you might know that Triton's is the next densest. But what's the third? Fourth? Do any other moons even have atmospheres? In fact, they do; and one such atmosphere has just been discovered.

An internal ocean on Ganymede: Hooray for consistency with previous results!

Emily Lakdawalla • March 12, 2015

A newly published paper confirms a subsurface ocean at Ganymede. An ocean there was already suspected from its magnetic field and predicted by geophysics; new Hubble data confirms it, and even says it is in the same place we thought it was before. Such consistency is rare enough in planetary science to be worth celebration.

Some Recent Views of Mars from Hubble

Mars Orbiter Mission delivers on promise of global views of Mars

Emily Lakdawalla • September 29, 2014

Ever since I first learned about the capabilities of Mars Orbiter Mission's small payload of science instruments, I have been anticipating one type of data in particular: global color views of Mars captured in a single 2000-pixel-square frame. Just days after entering orbit, Mars Orbiter Mission has delivered on that promise.

Hubble to the rescue! The last-ditch effort to discover a Kuiper belt target for New Horizons

Emily Lakdawalla • June 17, 2014

Will New Horizons have a mission after Pluto? Ground-based searches have failed to turn up anything that New Horizons can reach. Now Hubble is joining the search, but time is running out: a discovery must be made within the next two months.

Predicting Pluto's moons and moondust

Emily Lakdawalla • February 19, 2014

Why didn't we discover Pluto's moons until more than a decade after Hubble launched? Mark Showalter helps me answer this question.

Super-close supernova in M82

Emily Lakdawalla • January 22, 2014

The astronomy world is all a-twitter this morning over the discovery of a new supernova in M82, a galaxy that's in our astronomical backyard, "only" 12 million light-years away. And early word is that it appears to be a Type Ia supernova, the kind that's used as a standard candle to measure the expansion of the universe.

Snow balls in space

Mike Brown • December 29, 2013

I don’t get much snow in southern California, but I do spend a lot of my time thinking about college snowball experiences and about the snowball fights that have made the objects of the outer solar system.
