A recent Hubble image of the galaxy IC 335 shows it to be a star-filled galaxy with a flat shape not unlike our own Milky Way. But whereas the Milky Way contains vast collections of nebulae and dust clouds, IC 335 seems to have none. A look behind the curtain gives us clues to how two similar galaxies like IC 335 and the Milky Way could turn out so differently.
The planets Venus and Jupiter return to the evening skies this January. Jupiter will be rising in the east as Venus sets in the west. Both planets will be so incredibly bright that you might mistake them for something else...
If you are a planetary scientist, you are having one of your best years... ever! Beyond the drama of the images, the technology that makes them possible is also amazing. How could anyone NOT be excited by the exploration of our solar system? Who needs the distant stars... for now.
It was a blistering 35 degrees Celsius, but I was so preoccupied by my new surroundings that I barely noticed the heat. As I started the ignition of my rental car, my nerves tingled. I'm alone, in the desert. I'm going to be driving around in the desert, alone.
Over the next several weeks -- as we navigate mall parking lots, fill our shopping carts and test our patience in check-out lines -- let's not lose sight of what's behind this excitement. It all comes down to the simple act of giving.
Half of all Americans, including more than three-quarters of white evangelicals, believe the End Times are upon us! But, seeing as the clearest prophecy in the Bible, attributed to Jesus himself, went unfulfilled, maybe we need think harder.
About 450 light-years from Earth, in the constellation Taurus, a dense, dark, interstellar cloud has slowly started to reveal its secrets. The addition of new high-resolution data like that for the star HL Tau is at long last allowing astronomers to see the hidden details of planet and disk formation and, from this, create the next-generation physics-based models for how planets form.
Can comets hit Earth? As a scientist who helped launch vehicles into Space, I wondered the answer to this question too. Recently the comet named Si...
Thinking about whether a particular set of religious practices or beliefs would make sense on a different planet might be a valuable exercise in understanding ourselves.
Robotic telescopes constantly collect astronomical data and generate enormous astronomical databases. But these huge databases are of almost no value unless there are tools that can analyze them and turn them into knowledge.
When the Moon is totally in the Earth's shadow, called totality, the Moon will turn an eerie shade of red as sunlight bends through the Earth's atmosphere to reach it. After totality, the Earth's shadow will slowly wipe off the Moon and return it to its normal, full self.
It will be fun to see what turns up in the Rosetta and Philae images and data from Comet 67P/Churyumov-Gerasimenko! Astronomy is always full of surprises when you see something at high resolution for the first time.
Four hundred five years ago this week, Galileo Galilei demonstrated his new telescope to members of the Venetian senate in the Plaza San Marco. This presentation on Aug. 25, 1609, marks the birth of the astronomical telescope and the launching of a scientific revolution.
The sun (Helios) was the divine king of the sky for the Greeks. According to the "Homeric Hymn" of Helios: The sun shines his light on both men and im...
An ambitious campaign by the space fundraising group Uwingu starts today that will allow participants to beam a message to Mars.
Do you want conspiracy theorists to create the nation's scientific research agenda? Does it make sense to take their bizarre views seriously?
