#Hubble30 In 2003 Hubble released this stunning image of the Omega Nebula. The wave-like patterns of gas have been sculpted and illuminated by a torrent of ultraviolet radiation from young, massive stars, which lie outside the picture to the upper left: https://t.co/SO4bzuLqi8 https://t.co/bk65ZB1lVp

#Hubble30 Using its newly installed Advanced Camera for Surveys, Hubble captured this image of the Cone Nebula in 2002. The pillar of gas and dust is being slowly eroded away by radiation from nearby stars, but new stars may form in its densest regions: https://t.co/SO4bzuLqi8 https://t.co/EhBBwMm6HX

#Hubble30 Released in 2001, this Hubble image shows the Horsehead Nebula, a cold, dark cloud of gas and dust silhouetted against a bright nebula. The top of the Horsehead is sculpted by radiation from a massive star located outside the field of view: https://t.co/SO4bzuLqi8 https://t.co/5t9DOMTucq

#Hubble30 Hubble released this image of the planetary nebula NGC 6751 in 2000. Glowing in the constellation Aquila like an eye, the nebula is a cloud of gas ejected several thousand years ago from the star at its center. It is nearly a light-year across: https://t.co/SO4bzuLqi8 https://t.co/yc7VTrVPnQ

#Hubble30 In this Hubble image, released in 1999, the volcanic moon Io appears against the face of Jupiter. Bright patches on Io are regions of sulfur dioxide frost. The black dot next to Io is the moon’s shadow cast on Jupiter: https://t.co/SO4bzuLqi8 https://t.co/DT5gVZR8kh

#HubbleFriday Although it may appear peaceful in the silent emptiness of space, spiral galaxy NGC 4651 is keeping a violent secret. To become the large & beautiful spiral that we see here, it is believed that this galaxy consumed another smaller galaxy: https://t.co/GfNVYNPT0I https://t.co/2vqkOaOmff

#Hubble30 This false-color image of Saturn, taken in 1998, captures infrared light reflecting off the planet. It reveals information about Saturn’s atmosphere and shows two of the planet’s moons: Dione in the lower left & Tethys in the upper right: https://t.co/SO4bzuLqi8 https://t.co/Z1DvUd6tSN

Astronomers have found the best evidence yet for a black hole of an elusive class known as "intermediate mass." This mid-sized black hole betrayed its existence by tearing apart a wayward star that passed too close: https://t.co/mBhZFtmHwx https://t.co/42p5FaTtaL

#Hubble30 In 1996 Hubble released this image of the galaxy cluster 0024+1654, which acts as a gravitational lens, bending light from an even farther galaxy. Several blue, loop-shaped images of the distant galaxy appear around the cluster’s center: https://t.co/SO4bzuLqi8 https://t.co/Q8XvUTqhLU

#Hubble30 In 1995 Hubble captured eerie, pillar-like structures in the Eagle Nebula. These columns of gas and dust are incubators for new stars. The tallest one is about 4 light-years long: https://t.co/vw0EUHIOT7 https://t.co/pONNCeZvnM

#Hubble30 In 1994 Hubble released this view of galaxy M100 taken by the Wide Field and Planetary Camera 2. Installed during Hubble’s first servicing mission, the camera had corrective optics, allowing it to image the galaxy with unprecedented clarity: https://t.co/vw0EUHIOT7 https://t.co/XRw9HAzeCb

#Hubble30 In 1993 Hubble released this view of the Cygnus Loop supernova remnant, the edge of a bubble-like blast wave from a stellar explosion. The blast wave is slamming into clouds of gas, compressing and heating them, which causes them to glow: https://t.co/IXKcbpnhvM https://t.co/DxDYYm8451

#Hubble30 In 1992 Hubble investigated the supermassive black hole in galaxy NGC 4261. This debris disk, which is 300 light-years across, surrounds the black hole. Material is heated to millions of degrees as it is pulled toward the black hole: https://t.co/meXKU9mMNw https://t.co/Sj6u4hFnry

#HubbleFriday NGC 4618 was discovered in 1787 by astronomer William Herschel, who thought the fuzzy-looking object might be a distant star cluster. In reality, it's a one-armed barred spiral galaxy about 21 million light-years from our galaxy: https://t.co/CfQLB2eVZ2 https://t.co/DIKbasMWxR

#Hubble30 In 1991 Hubble released its first true-color image of Jupiter, capturing the planet in unprecedented detail. Since then, regular observations of the gas giant have allowed scientists to study the dynamic cloud system in its atmosphere: https://t.co/TIdAt6VJxb https://t.co/HSrQY8F9hJ

#Hubble30 For the next 30 days, we’ll be counting down to Hubble’s 30th anniversary, sharing one great image for each year of Hubble’s career. We’ll start today with an image from 1991 to celebrate Hubble’s first birthday & end with 2020, when we’ll reveal Hubble’s newest image! https://t.co/U3kA6JDrHR
