Blogs

Welcome to the Adler's Blogs! Adler Transmissions provides you with the latest news and views from Adler's astronomers, curators, partners, and programming staff. From Earth to distant planets and beyond, This Week in Space discusses the latest discoveries and accomplisments in science, space, and technology.

Astronomers Confounded By Massive Rocky World

Astronomers have discovered a rocky planet that weighs 17 times as much as Earth and is more than twice as large in size. This discovery has planet formation theorists challenged to explain how such a world could have formed.

Sunsets on Titan Reveal the Complexity of Hazy Exoplanets

Scientists working with data from NASA’s Cassini mission have developed a new way to understand the atmospheres of exoplanets by using Saturn’s smog-enshrouded moon Titan as a stand-in. The new technique shows the dramatic influence that hazy skies could have on our ability to learn about these alien worlds orbiting distant stars.

The Making of NASA's Global Selfie: 100+ Countries, Thousands of Photos

On Earth Day this year, NASA asked people all around the world a simple question – “Where are you on Earth Right Now?” The goal was to use each picture as a pixel in the creation of a “Global Selfie” – a mosaic image that would look like Earth appeared from space on Earth Day. Today NASA released the finished product.

Our Sun Now has a Brother Star, the First One Ever Found

Astronomers at the University of Texas have identified the first sibling of our Sun. We knew our Sun had siblings; in other words, we knew the Sun was born from a large cloud of gas and dust in space from which other stars doubtless emerged as well. But this is the first brother star to the Sun astronomers have pinpointed so far.

Nearest Hypervelocity Star Found Speeding Through Space at 1 Million Mph

Astronomers think hypervelocity stars happen when the galaxy’s central back hole captures one of two stars in a binary system and slingshots the other out of the galaxy.

Planck Takes Magnetic Fingerprint of our Galaxy

A new image from the Planck space telescope reveals the magnetic field lines of our Milky Way galaxy. The fingerprint-like map allows astronomers to study the structure of the magnetic field and better understand the process of star formation.

The Intergalactic Medium Unveiled: Cosmic Web Imager Directly Observes 'Dim Matter'

Caltech astronomers have taken unprecedented images of the intergalactic medium (IGM) -- the diffuse gas that connects galaxies throughout the universe -- with the Cosmic Web Imager, an instrument designed and built at Caltech.

15th Annual Webster Lecture on Archaeoastronomy

In 1962, Roderick and Marjorie Webster discovered a passion for historic scientific instruments when, on a whim, Roderick purchased an old sundial while running errands.

NASA's Kepler Discovers First Earth-Size Planet In The 'Habitable Zone' of Another Star

Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet.

Cosmos and the Dialog between Science and Religion

The first episode set the stage for the journey, with a brief tour through our vast Universe in space and time. Of course it is a daunting job to do full justice to both the science and the human history of science, and it is perhaps not surprising that the episode takes a one-sided view in its depiction of the interaction between religion and science, particularly in the sequence depicting Bruno’s tragic clash with the Inquisition.

Faraway Moon or Faint Star? Possible Exomoon Found

NASA-funded researchers have spotted the first signs of an "exomoon," and though they say it's impossible to confirm its presence, the finding is a tantalizing first step toward locating others. The discovery was made by watching a chance encounter of objects in our galaxy, which can be witnessed only once.

Sundial Makers and Techniques

The sundials on display in the new exhibition Saving Time: Collecting and Conserving Sundials highlight exquisite craftsmanship by important sundial makers, such as Paul Reinmann, Johann Martin, and Johann Willebrand. These instrument makers were known for their elegant, well-made dials.

Mercury has a Long History of Exploding Volcanoes

Considering the fact that Mercury wasn’t supposed to have explosive volcanism in the first place, the findings from a new analysis are surprising, and could have implications for understanding how the planet formed.

Eclipses this April and throughout History

Eclipses are among the most spectacular and easily viewed astronomical events. Nothing is required but a clear sky, and even the most unobservant person who happens to be out-of-doors when one takes place is likely to notice these dramatic encounters between the two brightest objects in our sky: the Sun and the Moon.

NASA Space Assets Detect Ocean inside Saturn Moon

NASA's Cassini spacecraft and Deep Space Network have uncovered evidence that Saturn's moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the Moon as a potential home to extraterrestrial microbes.

Night Sky as Milky Way and Andromeda Galaxies Merge

As seen on the Cosmos TV series featured in 2014, the Milky Way galaxy and the nearby Andromeda galaxy will collide and merge 4 billion years from now. Check out this video from the Hubble Space Telescope news center to see the predicted merger between our two titan spiral galaxies, as seen in Earth’s sky.
