Giant ridges on the surface of landslides on Mars could have formed without ice, challenging their use by some as unequivocal evidence of past ice…
Study reports on search for an atmosphere around a planet somewhat similar to ours. Astronomers at MIT, Harvard University, and elsewhere have searched a rocky,…
Lost in the glare following the Apollo 11 Moon landing, two intrepid robotic spacecraft flew by Mars in the summer of 1969 and returned photographs…
How can a planet be “hotter than hot?” The answer is when heavy metals are detected escaping from the planet’s atmosphere, instead of condensing into…
A piping hot planet discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS) has pointed the way to additional worlds orbiting the same star, one of…
NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite (TESS), has discovered three new worlds — one slightly larger than Earth and two of a…
NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered 21 planets outside our solar system and captured data on other interesting events occurring in the southern…
The Moon’s south pole region is home to some of the most extreme environments in the solar system: it’s unimaginably cold, massively cratered, and has…
All atoms and molecules emit distinctive spectral lines across the spectrum, the details of which depend on the internal structures of the species (for example,…
A team of astronomers led by the Harvard-Smithsonian Center for Astrophysics have updated and confirmed self-lensing binary star KOI-3278’s companion to be a white dwarf…
Southern California got all shook up after a set of recent quakes. But Earth isn’t the only place that experiences quakes: Both the Moon and…
In recent years, the idea of life on other planets has become less far-fetched. NASA announced June 27 that it will send a vehicle to…
People have long dreamed of altering the Martian climate to make it livable for humans. Carl Sagan was the first outside the realm of science…
Two NASA space telescopes have teamed up to identify, for the first time, the detailed chemical “fingerprint” of a planet between the sizes of Earth…
NASA successfully demonstrated Tuesday the Orion spacecraft’s launch abort system can outrun a speeding rocket and pull astronauts to safety during an emergency during launch….
NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered a world between the sizes of Mars and Earth orbiting a bright, cool, nearby star. The planet,…
The frigid lakeshores of Saturn’s moon Titan might be encrusted with strange, unearthly minerals, according to new research being presented here. Scientists re-creating Titan-esque conditions…
The Kepler mission and its extension, called K2, discovered thousands of exoplanets. It detected them using the transit technique, measuring the dip in light intensity…
