The Galaxy, the Jet, and the Black Hole

Explanation: Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured by planet Earth's Event Horizon Telescope in the first ever image of a black hole. Giant of the Virgo galaxy cluster about 55 million light-years away, M87 is the large galaxy rendered in blue hues in this infrared image from the Spitzer Space telescope. Though M87 appears mostly featureless and cloud-like, the Spitzer image does record details of relativistic jets blasting from the galaxy's central region. Shown in the inset at top right, the jets themselves span thousands of light-years. The brighter jet seen on the right is approaching and close to our line of sight. Opposite, the shock created by the otherwise unseen receding jet lights up a fainter arc of material. Inset at bottom right, the historic black hole image is shown in context, at the center of giant galaxy and relativistic jets. Completely unresolved in the Spitzer image, the supermassive black hole surrounded by infalling material is the source of the enormous energy driving the relativistic jets from the center of active galaxy M87.

New Music From Bruce Springsteen, The Black Keys And More

Plus, Conor Oberst and Phoebe Bridgers return to the Tiny Desk

Some weeks, the amount of new music we’re hearing is simply astounding. Take this week: To kick things off, The Black Keys released a single and announced a new album, Let’s Rock. Lucy Dacus shared a heartfelt reflection on mothers and daughters for Mother’s Day (and Taurus season). Plus, Kevin Abstract released yet another track before dropping his new album, ARIZONA baby.

It didn’t stop there. As Thursday turned to Friday, Bruce Springsteen released “Hello Sunshine” from his upcoming record, Western Stars, his first new studio album in five years. And not to be outdone, Taylor Swift quelled months of Instagram-fueled speculation with a new track (and video), “ME!” It’s tough to keep up, but hey, we’ll keep listening.

From our headphones to yours,

New Music

  • Didn’t get enough new music for your latest playlist? We’ve got even more. This week, FKA twigs rebuilt her signature sound with a new song and video, “Cellophane,” and ScHoolboy Q dropped a new album, CrasH Talk. Plus, you can hear about our favorite new albums out this week on New Music Friday from All Songs Considered.
  • This week in our First Listen series: Stream The Felice Brothers’ take on our modern times, Rhiannon Giddens’ explorations of heartfelt exchange and private longing, the debut album from Tank and the Bangas (winner of the 2017 Tiny Desk Contest), and more great records ahead of their release.

Featuring

  • In the latest edition of her All Ears column, an occasional look at ideas in electronic and experimental music, Ruth Saxelby considers the emotional power of non-verbal vocals.
  • With “Smells Like Teen Spirit,” Nirvana mocked mainstream rock songs — but the song ended up becoming a smash hit anyway. The latest in our American Anthem series examines the anthem for a generation that didn’t want one.

Tiny Desk

We rarely hosts artists more than once at the Tiny Desk, but it’s always a delight to see a familiar face. So when Conor Oberst and Phoebe Bridgers — both alumni of the Tiny Desk — teamed up as Better Oblivion Community Center, we knew it would make for a great Tiny Desk concert. What we didn’t expect was a guest feature from Bob Boilen, who joined the band for one track to provide some surprising background ambience.
