Nearly a year ago, the ALMA collaboration released this stunning image of the young star HL Tau. The sub-millimeter wavelengths of light that ALMA detects revealed a vast disc of gas and dust, several times larger than Neptune’s orbit. Intriguingly, the disc was divided up into a series of well-defined, concentric rings.
The cause of the rings seemed clear: There must be planets around HL Tau, their gravity sculpting the gas and sweeping out the dark gaps in the disc.
When the stars align, you just might catch a planet, a black hole, or a binary star—but it’s hard to measure its mass! What does it take to do so?
There are more moons than planets in our Solar System that harbor liquid water, and these moons may offer us the best chances of finding life off of Earth. Today’s paper takes the search for habitable moons a step further by investigating how telescopes of the near future might allow us to see and characterize these moons around exoplanets.
This month’s undergraduate research post features a student who looked at how well LSST will be able to detect transiting exoplanets. Read on to find out what she learned!
Finding extraterrestrial intelligence would be one of the most enlightening and profound discoveries in history. Today’s post looks at two potential means of finding extraterrestrials by seeing their advanced technology elsewhere in the Milky Way and the Universe.
Last year, an image was released that took our breath away. Exquisite rings carved in a disk of material around a nearby star. Now, astronomers want to know if forming planets are responsible, and why the image might look different from the cartoon in your textbook.
